Affected Products

Product | Affected Versions

Linux Kernel | [Insert affected version]

How the Exploit Works

The vulnerability arises from a use-after-free (UAF) issue in the print_graph_function_flags() function within the Linux kernel’s tracing component. During ftrace stress testing, tracer switching only updates one of the two calls to print_graph_function_flags, leaving the second to use the print_line function of the old tracer.
When switching tracers, ‘iter->private’ is freed but not set to NULL, providing an opportunity for an invalid ‘iter->private’ to be used. This can lead to undefined behavior and potentially be exploited to execute arbitrary code or cause a denial of service.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is not actual exploit code, but a representation of the steps an attacker might take.

# Switch to the function_graph tracer
echo function_graph > current_tracer
# Start a background process that reads the trace
cat trace > /dev/null &
# Ensure the 'cat' reaches the 'mdelay(10)' point
sleep 5
# Switch to the 'timerlat' tracer, triggering the vulnerability
echo timerlat > current_tracer

Mitigation Guidance

The most effective mitigation for this vulnerability is to apply the patch provided by the vendor. Users and administrators should update their Linux kernels to the latest patched version as soon as possible.
In the meantime, or in situations where immediate patching is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These can help detect and block attempts to exploit the vulnerability.
Understanding and addressing cybersecurity vulnerabilities like CVE-2025-22035 is crucial for maintaining the security and integrity of systems and data. Stay informed and proactive in your cybersecurity practices to protect your systems against potential threats.

Overview

Vulnerability Summary

CVE ID: CVE-2025-40908
Severity: Critical (CVSS 9.1)
Attack Vector: Local
Privileges Required: Low
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Perl YAML-LibYAML | Prior to 0.903.0

How the Exploit Works

The vulnerability stems from the usage of a two-argument open function in Perl YAML-LibYAML. This function is capable of opening a file for either reading or writing. However, it does not properly validate the file path, which allows an attacker to manipulate it and modify existing files. Consequently, this can lead to unauthorized alterations of data, potential system compromise, or even data leakage.

Conceptual Example Code

An attacker could potentially exploit this vulnerability as shown in the pseudocode below:

# Pseudocode demonstrating the exploit
use YAML::LibYAML;
my $filename = "| rm -rf /"; # Arbitrary command to demonstrate potential damage
open(my $fh, ">", $filename); # Open the file for writing
print $fh "malicious content"; # Write malicious content to the file

In this example, the attacker is exploiting the lack of validation of the `$filename` variable in the `open` function to execute the `rm -rf /` command, which could potentially delete all files in the system.

Mitigation

To mitigate this vulnerability, users are advised to apply the vendor patch for Perl YAML-LibYAML 0.903.0 as soon as possible. In the interim, usage of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure to detect and block potential exploit attempts. Additionally, developers should ensure that they use the three-argument version of the `open` function, which doesn’t suffer from this vulnerability.

Overview

In the constantly evolving landscape of cybersecurity, a new vulnerability has been discovered that affects Zitadel, an open-source identity infrastructure software. Identified as CVE-2025-48936, this vulnerability presents certain risks to users and poses a significant threat to the security of their accounts. The vulnerability exists in the password reset mechanism of Zitadel versions prior to 2.70.12, 2.71.10, and 3.2.2. The implications of this flaw are substantial, potentially leading to system compromise or data leakage, making it a critical issue to be addressed promptly.

Vulnerability Summary

CVE ID: CVE-2025-48936
Severity: High – CVSS Score 8.1
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Zitadel | Prior to 2.70.12
Zitadel | Prior to 2.71.10
Zitadel | Prior to 3.2.2

How the Exploit Works

The exploit takes advantage of a flaw in the password reset mechanism of Zitadel. The software uses the Forwarded or X-Forwarded-Host header from incoming requests to construct the URL for the password reset confirmation link that is emailed to the user. If an attacker can manipulate these headers, for instance, via host header injection, they could cause Zitadel to generate a password reset link pointing to a malicious domain under their control. If the unsuspecting user clicks this manipulated link, the secret reset code embedded in the URL can be captured by the attacker. This code can then be used to reset the user’s password and gain unauthorized access to their account.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. The attacker sends a malicious HTTP request manipulating the “X-Forwarded-Host” header:

POST /password/reset HTTP/1.1
Host: victim.example.com
X-Forwarded-Host: attacker.com
Content-Type: application/json
{ "email": "victim@example.com" }

This causes the password reset email to include a link pointing to the attacker’s domain, which enables them to capture the user’s reset code.

Overview

In the world of software, security vulnerabilities are a common occurrence. One such vulnerability, identified as CVE-2025-48477, affects FreeScout, a free self-hosted help desk and shared mailbox. FreeScout has become a popular tool for many organizations due to its cost-effectiveness and ease of use. However, this vulnerability poses a significant risk, potentially leading to system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-48477
Severity: High (8.1 CVSS Severity Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

FreeScout | Prior to 1.8.180

How the Exploit Works

The vulnerability arises due to an improper sequence of actions required to implement a functional capability. The application allows access to this functional capability without properly completing one or more actions in the sequence. As a result, an attacker can manipulate the attributes of a Mailbox object using the fill method. This could potentially lead to unauthorized system access or data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request where the attacker sends a malicious payload to a vulnerable endpoint.

POST /mailbox/attributes HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "mailbox_attributes": "malicious_payload" }

In this example, the attacker is sending a “mailbox_attributes” request with a malicious payload to the target server. Since the application does not properly check the sequence of actions, it accepts and processes the request, leading to the manipulation of the Mailbox object’s attributes.

Mitigation Guidance

Users of affected versions of FreeScout are strongly advised to upgrade to version 1.8.180 or later, which includes a patch for this vulnerability. If for some reason an immediate upgrade is not feasible, using a web application firewall (WAF) or intrusion detection system (IDS) can serve as a temporary mitigation. It’s important to note that these are just temporary measures and won’t provide complete protection against potential exploits. Therefore, upgrading to a patched version should be the primary course of action.

Overview

The CVE-2025-31189 is a critical vulnerability that affects certain versions of macOS, namely Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5. This vulnerability allows an application to potentially break out of its sandbox, leading to possible system compromise or data leakage. The impact of this vulnerability is far-reaching, given the number of systems running these versions of macOS and the potential damage that can be caused if the vulnerability is exploited. Therefore, it’s imperative for users and administrators to understand this vulnerability and take the necessary steps to mitigate it.

Vulnerability Summary

CVE ID: CVE-2025-31189
Severity: High (8.2 CVSS score)
Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

macOS Ventura | Prior to 13.7.5
macOS Sequoia | Prior to 15.4
macOS Sonoma | Prior to 14.7.5

How the Exploit Works

The exploit takes advantage of a weakness in the file quarantine system of the affected macOS versions. In normal operations, macOS uses sandboxing to restrict an application’s access to system resources and data. However, this vulnerability allows an application to bypass these restrictions. If an attacker can get a user to run a malicious application, the application can break out of its sandbox and gain unauthorized access to system resources and data.

Conceptual Example Code

A conceptual example of how the vulnerability might be exploited is an application that sends a request to change its own sandbox restrictions, like this:

$ sandbox-exec -n no-network /path/to/vulnerable/application
# The malicious app then performs actions it normally wouldn't be able to:
$ touch ~/Documents/ImportantFile
$ echo "Sensitive data" > ~/Documents/ImportantFile

This conceptual example illustrates how a malicious app could break out of its sandbox and perform actions it normally wouldn’t be able to, such as creating and writing to a file in the user’s Documents folder.
In this example, `sandbox-exec -n no-network /path/to/vulnerable/application` is a command that an attacker could use to execute the malicious app with sandbox restrictions in place, and the subsequent commands are examples of actions the app could perform after bypassing these restrictions.

Attack Vector: Network
Privileges Required: Low (Contributor-level access)
User Interaction: Required
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Offsprout Page Builder Plugin for WordPress | 2.2.1 to 2.15.2

How the Exploit Works

The exploit takes advantage of insufficient authorization checks in the permission_callback() function of the Offsprout plugin. An attacker with Contributor-level access or above is able to send crafted requests that modify the user meta data. This could include changing their own wp_capabilities to that of an administrator, thus allowing them to perform any administrative task on the WordPress site. This includes reading, creating, updating, or deleting any content on the site.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited using a crafted HTTP request to the vulnerable endpoint.

POST /wp-json/offsprout/v1/users/1 HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [access_token]
{
"meta": {
"wp_capabilities": {
"administrator": "1"
}
}
}

In this example, the attacker sends a POST request to the Offsprout endpoint for user updates. The request includes a JSON body that changes the wp_capabilities of the user to administrator. This would grant the attacker full administrative privileges on the WordPress site.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the latest patch provided by the vendor. If a patch is not immediately available, using a Web Application Firewall(WAF) or Intrusion Detection System(IDS) can provide temporary protection by identifying and blocking malicious requests.

Vulnerability Summary

CVE ID: CVE-2025-4103
Severity: High (8.8)
Attack Vector: Network
Privileges Required: Low (Subscriber-level access)
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

WP-GeoMeta Plugin for WordPress | 0.3.4 to 0.3.5

How the Exploit Works

The vulnerability resides in the `wp_ajax_wpgm_start_geojson_import()` function of the WP-GeoMeta plugin. This function lacks a necessary capability check, which means that it does not properly verify the permissions of the user making the request. As a result, a malicious actor with Subscriber-level access could exploit this oversight to perform administrative actions, like uploading malicious files, changing site settings, or even creating new admin-level user accounts.

Conceptual Example Code

The following is a conceptual example of how an attacker could exploit this vulnerability. This is a hypothetical HTTP request that might be sent by an attacker already authenticated as a subscriber:

POST /wp-admin/admin-ajax.php?action=wpgm_start_geojson_import HTTP/1.1
Host: targetsite.com
Content-Type: application/json
Cookie: wordpress_logged_in_[hash]=[username]|1434730000|abcdef1234567890abcdef1234567890
{
"importData": {
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"title": "Injected Admin Account",
"role": "administrator",
"username": "attacker",
"email": "attacker@example.com",
"password": "P@ssw0rd!"
}
}
]
}
}

In this example, the attacker is exploiting the vulnerability to create a new admin-level user account under their control.

Mitigation

Users of the WP-GeoMeta Plugin for WordPress should apply the latest vendor patch to mitigate this vulnerability. If a patch is not yet available, users should consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to provide temporary protection against potential exploitation of this vulnerability. Regularly monitoring system logs for any suspicious activity is also strongly recommended.

Overview

In the realm of WordPress plugins, a new vulnerability has been identified which poses significant threats to users of the Profitori plugin. This vulnerability, known as CVE-2025-4631, exposes these users to a potential privilege escalation exploit. In essence, this means that an unauthenticated attacker could potentially elevate the privileges of an existing user account, or even a newly created one, to that of an administrator.

Vulnerability Summary

CVE ID: CVE-2025-4631
Severity: Critical (CVSS: 9.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System Compromise, Potential Data Leakage

Affected Products

Product | Affected Versions

Profitori WordPress Plugin | 2.0.6.0 to 2.1.1.3

How the Exploit Works

The vulnerability lies in the stocktend_object endpoint of the Profitori plugin for WordPress. This endpoint lacks a necessary capability check, which results in the triggering of the save_object_as_user() function for objects whose ‘_datatype’ is set to ‘users’. As a result, this allows unauthenticated attackers to write arbitrary strings straight into the user’s wp_capabilities meta field.
In simpler terms, the absence of a check mechanism allows attackers to manipulate user capabilities, potentially elevating a user’s privileges to that of an administrator. Consequently, this can lead to unauthorized access to sensitive data and potentially compromise the entire system.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

POST /stocktend_object HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"_datatype": "users",
"wp_capabilities": "{administrator:1}"
}

In this example, an attacker sends a malicious HTTP POST request to the stocktend_object endpoint. By setting the _datatype to ‘users’ and manipulating the wp_capabilities meta field, the attacker could potentially escalate user privileges to the administrator level.

Recommended Mitigation

To mitigate this vulnerability, users of the Profitori WordPress Plugin should apply the vendor patch as soon as possible. In case the patch is not immediately available, users can resort to using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) for temporary mitigation. However, this is intended only as a stopgap measure and not a long-term solution. The long-term solution would be to apply the vendor patch to close the vulnerability entirely.

Vulnerability Summary

CVE ID: CVE-2025-4607
Severity: Critical (9.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Full system compromise or data leakage

Affected Products

Product | Affected Versions

PSW Front-end Login & Registration Plugin for WordPress | Up to and including 1.12

How the Exploit Works

The vulnerability arises from the use of a weak, low-entropy OTP mechanism in the forget() function of the plugin. This function is responsible for initiating a password reset for a user. An unauthenticated attacker can manipulate this function to initiate a password reset for any user, including administrators, thereby gaining unauthorized access to user accounts. With elevated privileges, the attacker can then exert full control over the site.

Conceptual Example Code

An attacker could potentially exploit this vulnerability by sending a malicious HTTP POST request to the password reset endpoint on the target site. A conceptual example might look like this:

POST /wp-login.php?action=lostpassword HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
user_login=admin&redirect_to=&wp-submit=Get+New+Password

In this example, the attacker is attempting to reset the password for the ‘admin’ user. If successful, the attacker would then intercept the low-entropy OTP sent by the forget() function, reset the password, and gain admin privileges.

Remediation

Users are strongly advised to apply any available patches from the vendor as soon as possible. In the absence of a patch, consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation. This can help block malicious traffic attempting to exploit this vulnerability. Regular system auditing and monitoring for unusual activity can also aid in early detection and prevention of an exploit.

Affected Products

Product | Affected Versions

Valtimo | 11.0.0.RELEASE to 11.3.3.RELEASE
Valtimo | 12.0.0.RELEASE to 12.12.0.RELEASE

How the Exploit Works

The vulnerability in Valtimo allows unauthorized users to access and manipulate objects on the platform. This is due to a flaw in the security configuration of the platform, which allows all objects for which an object-management configuration exists to be listed, viewed, edited, created or deleted by unauthorised users. If the URLs of these objects are exposed via other channels, the contents of these objects can be viewed independent of their object-management configurations.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability. This might involve sending a malicious HTTP request to a vulnerable endpoint:

GET /object-management/api/objects/ HTTP/1.1
Host: target.example.com
Content-Type: application/json

In this example, the attacker sends a GET request to the object-management endpoint, potentially allowing them to list all objects for which an object-management configuration exists. With this information, they could then proceed to view, edit, create, or delete these objects without authorization.
