CVE-2025-58794: 
WordPress vulnerability analysis and mitigation

CVE-2025-58794 is a Cross-Site Request Forgery (CSRF) vulnerability in the "Notification for Telegram" WordPress plugin developed by rainafarai. It affects all versions through 3.5.1 (initially reported as through 3.4.6/3.5), with version 3.5.2 being the patched release. The vulnerability was reported by researcher Nguyen Xuan Chien on June 22, 2025, and publicly disclosed by Patchstack on September 5, 2025. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack, Red Hat CVE).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery) and arises from missing or insufficient CSRF token validation on one or more plugin actions within the Notification for Telegram WordPress plugin. An unauthenticated attacker can craft a malicious web page or link that, when visited by an authenticated WordPress administrator or privileged user, triggers unauthorized state-changing requests on the target site. No special privileges are required by the attacker, but user interaction from a privileged victim is necessary for exploitation. The vulnerability maps to OWASP Top 10 category A1: Broken Access Control (Patchstack).

Successful exploitation allows a malicious actor to force higher-privileged WordPress users (such as administrators) to execute unwanted actions under their current authentication session, such as modifying plugin settings or Telegram notification configurations. The primary impact is on integrity (low), with no direct confidentiality or availability impact. While the individual impact is limited, CSRF vulnerabilities in WordPress plugins are frequently leveraged in mass-exploit campaigns targeting thousands of sites regardless of their size or popularity (Patchstack).

There is no known public exploit code or evidence of active in-the-wild exploitation for CVE-2025-58794 at this time. The EPSS score is approximately 0.014% (0.000140), 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 rates this as low priority with no impactful threat, though CSRF vulnerabilities in WordPress plugins are noted as being used in mass-exploit campaigns (Patchstack).

1. Reconnaissance: Identify WordPress sites running the "Notification for Telegram" plugin at version 3.5.1 or earlier, using tools like WPScan or by inspecting publicly accessible plugin metadata.
2. Craft malicious request: Identify the vulnerable plugin action endpoint (e.g., an admin settings form) that lacks CSRF token validation.
3. Create forged page: Build a malicious HTML page containing a hidden form or JavaScript that automatically submits a crafted POST request to the target WordPress site's admin endpoint, triggering the desired plugin action (e.g., changing Telegram bot settings).
4. Deliver to victim: Trick an authenticated WordPress administrator into visiting the malicious page via phishing email, social engineering, or a compromised third-party site.
5. Action executes: The victim's browser automatically submits the forged request with their valid session cookies, causing the plugin to perform the unauthorized action on their behalf (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to plugin admin endpoints (e.g., wp-admin/admin-post.php or wp-admin/options.php) from unusual referrer origins or with no valid nonce/CSRF token.
• Application: Unexpected changes to Notification for Telegram plugin settings, such as modified Telegram bot tokens, chat IDs, or notification configurations, without corresponding administrator activity.
• Network: Requests to WordPress admin endpoints originating from external or unexpected referrer domains, particularly if the user agent or session pattern is inconsistent with normal admin activity.

The vendor has released version 3.5.2 of the Notification for Telegram WordPress plugin, which addresses this CSRF vulnerability. All users running version 3.5.1 or earlier should update to 3.5.2 or later immediately via the WordPress plugin dashboard. As a temporary workaround if updating is not immediately possible, administrators can deactivate the plugin until the update can be applied. Patchstack users can enable auto-update for vulnerable plugins to receive protection automatically (Patchstack).
