CVE-2026-25322 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the PublishPress Revisions WordPress plugin, specifically affecting versions up to and including 3.7.22. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting unauthorized requests to a web application, leveraging the user's active session. In this case, the vulnerability allows attackers to perform actions within the PublishPress Revisions plugin without the user's consent, potentially altering or manipulating content revisions. The vulnerability does not require the attacker to have direct access or credentials; instead, it relies on the victim being authenticated and visiting a maliciously crafted webpage. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed or scored by standard frameworks. No known exploits are currently reported in the wild, but the risk remains due to the nature of CSRF attacks and the widespread use of WordPress and its plugins. The vulnerability impacts the integrity of content management processes, as unauthorized changes to revisions could lead to misinformation, content defacement, or disruption of publishing workflows. The PublishPress Revisions plugin is widely used by organizations managing editorial workflows, making this vulnerability relevant to entities relying on WordPress for content management. The lack of available patches at the time of reporting emphasizes the need for immediate attention once fixes are released. The vulnerability highlights the importance of implementing anti-CSRF tokens and validating request origins within web applications and plugins.

For European organizations, the impact of CVE-2026-25322 centers on the potential compromise of content integrity and editorial workflows within WordPress environments using the PublishPress Revisions plugin. Unauthorized revision changes could lead to misinformation, publication of incorrect or malicious content, and disruption of content approval processes. This can damage organizational reputation, reduce trust among users and customers, and potentially lead to regulatory compliance issues, especially under GDPR if personal data is mishandled or exposed through manipulated content. The availability of the content management system could also be indirectly affected if attackers use the vulnerability to disrupt publishing operations. Since WordPress is widely adopted across Europe, particularly in media, education, and government sectors, the vulnerability poses a tangible risk. The absence of known exploits reduces immediate threat but does not eliminate the risk, especially as attackers often weaponize such vulnerabilities once disclosed. Organizations with high reliance on PublishPress Revisions for editorial control are particularly vulnerable to operational disruptions and content integrity issues.

1. Monitor PublishPress official channels for patches addressing CVE-2026-25322 and apply updates promptly once available. 2. Implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the PublishPress Revisions plugin endpoints. 3. Enforce strict session management policies, including short session lifetimes and re-authentication for sensitive actions within WordPress. 4. Review and harden WordPress security configurations, ensuring that anti-CSRF tokens (nonce fields) are properly validated in all plugin forms and requests. 5. Educate users and administrators about the risks of CSRF attacks and the importance of avoiding clicking on untrusted links while authenticated. 6. Conduct regular security audits and penetration testing focusing on plugin vulnerabilities and CSRF protections. 7. Limit plugin usage to trusted administrators and editors to reduce the attack surface. 8. Consider temporarily disabling or restricting the PublishPress Revisions plugin if immediate patching is not possible and the risk is deemed high. 9. Employ Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests. 10. Monitor logs for unusual revision activities that could indicate exploitation attempts.
