CVE-2025-64262 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Auto Prune Posts plugin developed by ramon fincken, affecting versions up to 3.0.0. CSRF vulnerabilities allow attackers to perform unauthorized actions on behalf of authenticated users by exploiting the trust a web application has in the user's browser. In this case, the Auto Prune Posts plugin lacks adequate CSRF protections, such as anti-CSRF tokens, enabling attackers to craft malicious requests that, when executed by an authenticated user, can trigger unintended pruning of posts or modification of plugin settings. The vulnerability is remotely exploitable without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact primarily affects confidentiality and integrity, as unauthorized changes to post pruning configurations could lead to data manipulation or exposure of sensitive information through unintended content removal or retention. There is no direct impact on availability. No patches or fixes have been published at the time of disclosure, and no known exploits are reported in the wild. The vulnerability was reserved on October 29, 2025, and published on November 13, 2025. The plugin is commonly used in WordPress environments to automate the pruning of posts, making it relevant for organizations managing content-heavy websites. Without mitigation, attackers could leverage this vulnerability to manipulate content management workflows, potentially undermining content governance and compliance policies.

For European organizations, the impact of CVE-2025-64262 can be significant, especially for those relying on the Auto Prune Posts plugin within WordPress environments to manage large volumes of content. Unauthorized pruning or modification of posts could lead to loss or alteration of critical information, affecting data integrity and potentially exposing sensitive content inadvertently. This could disrupt content management processes, damage organizational reputation, and lead to compliance issues under regulations such as GDPR if personal or sensitive data is mishandled. Although availability is not directly impacted, the integrity and confidentiality concerns could indirectly affect business operations, especially for media, publishing, and e-commerce sectors that depend on accurate and reliable content presentation. The absence of known exploits reduces immediate risk, but the lack of patches means the vulnerability remains exploitable. Attackers could target European organizations with high web presence or those with less stringent web security controls, increasing the risk of exploitation.

1. Monitor for official patches or updates from the plugin developer and apply them promptly once available. 2. Implement web application firewall (WAF) rules to detect and block suspicious CSRF attack patterns targeting the plugin’s endpoints. 3. Restrict administrative access to the WordPress backend using IP whitelisting or VPNs to reduce exposure. 4. Enforce strict user role management to limit the number of users with permissions to modify plugin settings. 5. Enable and verify the presence of anti-CSRF tokens in all forms and requests related to the Auto Prune Posts plugin; if missing, consider custom development or temporary disabling of the plugin. 6. Conduct regular security audits and penetration testing focusing on CSRF and other web vulnerabilities. 7. Educate users and administrators about the risks of CSRF and safe browsing practices to minimize the risk of social engineering attacks that could trigger CSRF exploits.
