Overview<\/strong><\/p>\n

The cybersecurity community has identified a dangerous vulnerability in the PeproDev Ultimate Profile Solutions plugin for WordPress that allows unauthorized data modification. This vulnerability, designated CVE-2025-3921, affects all versions of the plugin from 1.9.1 to 7.5.2. Given the widespread use of WordPress and the popularity of this plugin<\/a>, this vulnerability has the potential to impact a significant number of websites worldwide. The severity of this vulnerability<\/a> is highlighted by its ability to block administrators from accessing their sites, potentially leading to system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-3921
\nSeverity: High (8.2 CVSS Score)
\nAttack Vector: Remote
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Unauthorized access to and modification of user data, potential system<\/a> compromise and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

PeproDev Ultimate Profile Solutions plugin<\/a> for WordPress | 1.9.1 to 7.5.2<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the ‘handel_ajax_req()’ function of the plugin<\/a>, which lacks a capability check. This allows an unauthenticated attacker to update arbitrary<\/a> user metadata. The most damaging potential outcome of this is the ability to set ‘wp_capabilities’ to 0, effectively locking an administrator out of their own site.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability could be exploited, using a malicious HTTP POST request<\/a>:<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=peprodev_ultimate_profile_solutions_update HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"user_id\": \"admin\", \"meta_key\": \"wp_capabilities\", \"meta_value\": \"0\" }<\/code><\/pre>\n
In this example, the attacker is setting the ‘wp_capabilities’ of the ‘admin’ user to ‘0’, thereby stripping the administrator of their privileges.<\/p>\n
Recommendations for Mitigation<\/strong><\/p>\n
Users are recommended to apply the vendor patch as soon as possible to mitigate this vulnerability<\/a>. In the interim, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary measures to help guard against potential attacks exploiting this vulnerability<\/a>. Regularly updating and patching software is a key part of maintaining a robust cybersecurity defense<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
