CVE-2025-62958: 
WordPress vulnerability analysis and mitigation

CVE-2025-62958 is a Cross-Site Request Forgery (CSRF) vulnerability in the "Simple Content Templates for Blog Posts & Pages" WordPress plugin developed by Clifton Griffin. It affects all plugin versions up to and including 2.2.61, with no official patch available at the time of disclosure. The vulnerability was reported by researcher Trương Hữu Phúc (truonghuuphuc) on September 16, 2025, and published by Patchstack on October 16, 2025. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack VDP).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), arising from insufficient or absent CSRF token validation on one or more plugin action endpoints. An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user (such as an administrator or editor), silently submits a forged request to the vulnerable plugin endpoint on the victim's behalf. Exploitation requires user interaction — specifically, a privileged user must be tricked into clicking a malicious link or visiting a crafted page while authenticated to the WordPress site (Patchstack VDP).

Successful exploitation allows an attacker to perform unauthorized actions on behalf of an authenticated WordPress user without their knowledge or consent. Potential impacts include manipulation of blog post or page content templates, modification of plugin settings, and alteration of site content, all of which compromise the integrity of the WordPress installation. Confidentiality and availability are not directly impacted, as reflected in the CVSS score's zero ratings for those dimensions (Patchstack VDP).

There is no public proof-of-concept exploit code and no evidence of active in-the-wild exploitation at this time (Patchstack VDP). The EPSS score is extremely low at 0.000080, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority, noting it is unlikely to be exploited despite CSRF vulnerabilities of this type sometimes being used in mass-exploit campaigns targeting WordPress plugins.

1. Reconnaissance: Identify WordPress sites running the "Simple Content Templates for Blog Posts & Pages" plugin at version 2.2.61 or earlier, using tools like WPScan or passive enumeration.
2. Craft malicious payload: Create an HTML page containing a hidden form or JavaScript that automatically submits a forged HTTP request to the vulnerable plugin action endpoint (e.g., a settings update or template modification action) on the target WordPress site.
3. Social engineering: Deliver the malicious link or page to an authenticated WordPress administrator or editor via phishing email, comment, or other channel.
4. Trigger exploitation: When the victim visits the attacker-controlled page while logged into WordPress, the browser automatically sends the forged request with the victim's session credentials, causing the plugin to execute the unauthorized action (e.g., modifying content templates or plugin settings) (Patchstack VDP).

• Logs: WordPress access logs showing unexpected POST requests to plugin-related admin endpoints (e.g., wp-admin/admin-post.php or wp-admin/admin-ajax.php) from unusual referrer origins or with no referrer header.
• File System: Unexpected changes to content templates or plugin configuration files associated with the simple-post-template plugin directory.
• Logs: WordPress audit logs (if enabled via a security plugin) recording template or settings modifications by an authenticated user at unusual times or from unexpected IP addresses.

The primary remediation is to update the "Simple Content Templates for Blog Posts & Pages" plugin to a version newer than 2.2.61 once a patched release becomes available; as of the disclosure date, no official patch exists (Patchstack VDP). In the interim, site administrators should consider deactivating or removing the plugin if it is not essential. Additional mitigations include using a WordPress security plugin (e.g., Wordfence, Patchstack) that provides virtual patching or CSRF protection, ensuring admin users log out of WordPress sessions when not in use, and educating users to avoid clicking unknown links while authenticated.

The vulnerability was discovered and disclosed through Patchstack's Vulnerability Disclosure Program (VDP) by researcher Trương Hữu Phúc. Patchstack classifies it as low priority with no impactful threat, noting that no official patch is available (Patchstack VDP). No significant broader media coverage or notable community commentary has been identified for this vulnerability.
