CVE-2025-62866

Vulnerability

Overview

The WordPress Auto Alt Text plugin (versions 2.5.2 and earlier) contains a Cross-Site Request Forgery (CSRF) vulnerability [1]. This occurs because the plugin does not properly implement anti-CSRF tokens or other verification mechanisms for sensitive actions, allowing attackers to craft malicious requests that appear legitimate to the server [1].

Exploitation

Details

Exploitation requires user interaction: an authenticated administrator or other privileged user must be tricked into clicking a crafted link, visiting a specially prepared page, or submitting a malicious form while logged into the WordPress admin panel [1]. The attacker does not need any special privileges or network access beyond the ability to deliver the crafted request to the target user [1].

Impact

Successful CSRF exploitation can force the targeted privileged user to execute unwanted actions—such as changing plugin settings, altering auto-alt-text configurations, or performing other operations under their current authentication—without the user's knowledge or consent [1]. This could lead to data integrity issues or further compromise depending on the capabilities exposed in the plugin's administrative interface.

Mitigation

The issue has been addressed in plugin version 2.5.3, released after the disclosure. Users are strongly advised to update to version 2.5.3 or later immediately [1]. For sites where immediate update is not possible, administrators should review affected plugin settings and consider deactivating the plugin until an update can be applied [1].
