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

The CVE-2025-32569 is a deserialization of untrusted data vulnerability discovered in the TableOn – WordPress Posts Table Filterable plugin. This vulnerability poses a significant risk to WordPress websites running versions of the TableOn plugin up to and including 1.0.2. The severity of this vulnerability stems from its potential to grant unauthorized access to a system, potentially leading to system<\/a> compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-32569
\nSeverity: Critical (9.8 CVSS)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

TableOn – WordPress Posts<\/a> Table Filterable | up to and including 1.0.2<\/p>\n

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

The vulnerability arises from the improper handling of data by the TableOn<\/a> plugin. Specifically, the plugin fails to properly sanitize user input, which allows for the deserialization of untrusted data<\/a>. Attackers can exploit this vulnerability<\/a> by sending specially crafted requests to the affected websites. These requests contain malicious serialized objects that, when deserialized, can lead to code execution<\/a> in the context of the application, potentially leading to a full system compromise.<\/p>\n

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

Here is a conceptual example of how an attacker might exploit this vulnerability<\/a> with an HTTP request:<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=tableon_save_settings HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"settings\": \"YToxOntzOjI6InR0IjtpOjE7fQ==...\"\n}<\/code><\/pre>\n
In this example, the “settings” parameter contains a base64 encoded serialized PHP object that, when deserialized, triggers the execution of malicious code<\/a>.<\/p>\n
Mitigation and Recommendations<\/strong><\/p>\n
Organizations are recommended to immediately apply the vendor patch to remove the vulnerability. If a patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation. Regularly updating and patching software is a key part of maintaining secure systems and protecting against vulnerabilities<\/a> such as CVE-2025-32569.<\/p>\n","protected":false},"excerpt":{"rendered":"
