CVE-2025-64262 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Auto Prune Posts plugin by ramon fincken, affecting versions up to 3.0.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting unauthorized requests to a web application, leveraging the user's credentials and session. In this case, the Auto Prune Posts plugin, which automates the pruning of posts in content management systems (likely WordPress), does not adequately verify the origin or intent of requests that trigger pruning actions. This lack of verification enables attackers to craft malicious web pages or links that, when visited by an authenticated administrator or user with pruning privileges, cause unintended pruning operations. The vulnerability does not require the attacker to have direct access or credentials, only that the victim is logged in and visits a malicious site. No CVSS score has been assigned yet, and no public exploits are known. However, the potential for unauthorized content deletion or modification poses risks to data integrity and availability. The vulnerability was reserved in late October 2025 and published in November 2025, indicating recent discovery. The absence of patches at the time of publication suggests organizations must implement interim mitigations. The plugin's role in automated content management means exploitation could disrupt workflows and content availability, impacting organizational operations.

For European organizations, this vulnerability could lead to unauthorized deletion or modification of posts, disrupting content workflows and potentially causing data loss or service interruptions. Organizations relying on the Auto Prune Posts plugin for automated content management in WordPress environments may experience integrity and availability issues if exploited. This could affect internal communications, customer-facing content, or regulatory compliance if critical information is altered or removed. The ease of exploitation—requiring only that an authenticated user visits a malicious site—raises the risk of targeted attacks, especially in environments with multiple administrators or editors. Additionally, reputational damage and operational downtime could result from such disruptions. While confidentiality impact is limited, the integrity and availability impacts are significant. The lack of known exploits provides a window for proactive mitigation, but the risk remains high due to the nature of CSRF attacks and the plugin's administrative functions.

Organizations should immediately audit their use of the Auto Prune Posts plugin and restrict administrative access to trusted users only. Implementing web application firewalls (WAFs) with CSRF protection rules can help block malicious requests. Until an official patch is released, disabling the plugin or its auto-prune functionality may be necessary to prevent exploitation. Administrators should ensure that all user sessions are protected with anti-CSRF tokens and that the application enforces strict origin and referer header checks. Regularly monitoring logs for unusual pruning activity can help detect exploitation attempts early. Educating users about the risks of visiting untrusted websites while authenticated to administrative portals is also critical. Once patches become available, prompt application is essential. Additionally, organizations should review their incident response plans to address potential content integrity incidents stemming from this vulnerability.
