CVE-2025-64370: 
WordPress vulnerability analysis and mitigation

CVE-2025-64370 is a Missing Authorization (Broken Access Control) vulnerability in the YOP Poll WordPress plugin by YOP. It allows unauthenticated remote attackers to exploit incorrectly configured access control security levels. The vulnerability affects YOP Poll versions from n/a through 6.5.38 (inclusive). It was published on November 13, 2025, with Patchstack credited as the assigning authority. The CVSS v3.1 base score is 5.3 (Medium) (Feedly, ENISA EUVD).

The root cause is CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before executing certain actions or exposing functionality. This allows unauthenticated network-based attackers (no privileges or user interaction required) to interact with restricted plugin functionality, exploiting incorrectly configured access control levels. The attack vector is network-based with low complexity, making it straightforward to exploit without authentication (Feedly, Patchstack).

Successful exploitation results in a low integrity impact with no confidentiality or availability impact, meaning attackers can perform unauthorized actions within the plugin's scope — such as manipulating poll data or triggering restricted operations — without gaining access to sensitive data or disrupting service. The scope is unchanged, limiting the blast radius to the affected plugin's functionality on the WordPress installation. While not critical, unauthorized poll manipulation could affect the integrity of user-facing content on affected sites (Feedly).

Users should update the YOP Poll WordPress plugin to a version beyond 6.5.38, which is the last confirmed vulnerable release. Check the WordPress plugin repository or the vendor's official page for the latest patched release. As a general precaution, site administrators should review and restrict access to plugin-specific endpoints and monitor for unexpected poll data modifications (Patchstack, Feedly).
