CVE-2025-64262 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Auto Prune Posts plugin by ramon fincken, which is used to automate the pruning of posts in content management systems, likely WordPress. The vulnerability affects all versions up to and including 3.0.0. CSRF vulnerabilities allow attackers to induce authenticated users to perform unwanted actions on web applications without their knowledge, by exploiting the trust a site has in the user's browser. In this case, an attacker can craft malicious web requests that, when visited by an authenticated user, trigger the auto prune posts functionality without proper authorization checks. The CVSS 3.1 base score is 6.5, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). This means the vulnerability can be exploited remotely without credentials or user interaction, making it relatively easy to exploit. However, the impact is limited to partial disclosure or modification of data, specifically related to post pruning operations. No known exploits have been reported in the wild, and no patches have been released at the time of publication. The vulnerability was reserved on 2025-10-29 and published on 2025-11-13. The lack of patches and exploit code suggests organizations should proactively implement mitigations and monitor for suspicious activity.

For European organizations, especially those operating WordPress sites using the Auto Prune Posts plugin, this vulnerability could lead to unauthorized manipulation of content pruning processes. This can result in unintended deletion or retention of posts, potentially affecting data integrity and content availability indirectly. Confidentiality impact is low but present, as attackers might infer some information by triggering pruning actions. The integrity impact is moderate since unauthorized changes to post pruning settings or execution could disrupt content management workflows. Availability is not directly affected, but operational disruptions could occur if pruning is misused. Organizations relying heavily on automated content management or with strict content retention policies may face compliance risks or reputational damage if content is altered without authorization. The ease of exploitation and lack of required authentication increase the threat level, making it important for European entities to address this vulnerability promptly.

To mitigate CVE-2025-64262, organizations should: 1) Immediately audit their WordPress installations to identify if the Auto Prune Posts plugin (version ≤ 3.0.0) is in use. 2) Disable or remove the plugin if it is not essential until a patch is available. 3) Implement or verify the presence of anti-CSRF tokens in all state-changing requests related to post pruning. 4) Enforce strict origin and referer header validation to ensure requests originate from legitimate sources. 5) Restrict access to pruning functionality to authenticated users with appropriate roles and permissions, adding multi-factor authentication where possible. 6) Monitor web server logs and application logs for unusual or repeated pruning requests that could indicate exploitation attempts. 7) Stay updated with vendor announcements and apply patches immediately once released. 8) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious CSRF attack patterns targeting the plugin endpoints.
