CVE-2025-58794 Overview
CVE-2025-58794 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Notification for Telegram WordPress plugin by rainafarai. The flaw impacts all plugin versions up to and including 3.5. An attacker can trick an authenticated user into submitting unintended state-changing requests to the plugin. Successful exploitation requires user interaction, typically through a crafted link or malicious page. The vulnerability is classified under CWE-352 and stems from missing or improperly implemented anti-CSRF token validation on plugin request handlers.
Critical Impact
Attackers can force authenticated WordPress users to perform unauthorized plugin actions, leading to limited integrity impact on Telegram notification configurations.
Affected Products
- rainafarai Notification for Telegram plugin for WordPress
- All versions from n/a through 3.5
- WordPress installations with the notification-for-telegram plugin enabled

Technical Details for CVE-2025-58794
Vulnerability Analysis
The Notification for Telegram plugin exposes request handlers that perform state-changing operations without validating a request-origin token. WordPress provides wp_nonce_field() and check_admin_referer() for CSRF protection, but the affected plugin versions do not properly enforce these checks on all sensitive endpoints. An attacker who lures an authenticated administrator to a malicious page can trigger unauthorized configuration changes on the target site. The EPSS probability of exploitation stands at 0.131%, indicating low current exploitation likelihood, though the attack surface remains exposed on any unpatched installation.
Root Cause
The root cause is missing anti-CSRF token verification on plugin request handlers. Server-side handlers accept incoming POST or GET requests without confirming the request originated from a legitimate, authenticated user interface flow. This maps directly to CWE-352, Cross-Site Request Forgery.
Attack Vector
Exploitation requires an authenticated victim to interact with attacker-controlled content, such as clicking a crafted link or loading a malicious page. The browser automatically attaches WordPress session cookies to the forged request, causing the server to process the action under the victim's privileges. Because the flaw impacts integrity only at a low level, the practical outcome is limited to modifying plugin-specific settings such as Telegram notification targets or messaging behavior. No prior authentication is required from the attacker, but the victim must be logged into the target WordPress site at the time of the request.
Detection Methods for CVE-2025-58794
Indicators of Compromise
- Unexpected changes to Telegram bot tokens, chat IDs, or notification templates within the plugin configuration.
- WordPress access logs showing state-changing POST requests to notification-for-telegram endpoints with off-site or missing Referer headers.
- Outbound Telegram API traffic to unfamiliar chat IDs after an administrator visited a third-party site.
Detection Strategies
- Inventory WordPress installations and identify sites running notification-for-telegram at version 3.5 or earlier.
- Review web server logs for requests to plugin admin actions lacking a valid _wpnonce parameter.
- Correlate administrator browsing sessions with sudden plugin configuration changes recorded in the WordPress audit trail.
Monitoring Recommendations
- Enable a WordPress audit-logging plugin to record all changes to plugin settings and user actions.
- Alert on Telegram notification configuration modifications outside of change-management windows.
- Monitor for administrator sessions overlapping with visits to untrusted external domains.
How to Mitigate CVE-2025-58794
Immediate Actions Required
- Update the Notification for Telegram plugin to a version above 3.5 once the vendor publishes a fix, per the Patchstack advisory.
- If a patched version is not yet available, deactivate and remove the plugin from production WordPress sites.
- Rotate any Telegram bot tokens and chat IDs previously configured through the plugin to invalidate potentially exposed credentials.
Patch Information
At the time of publication, the vendor advisory tracked by Patchstack lists all versions through 3.5 as affected. Administrators should consult the Patchstack vulnerability report for the latest fixed-version information and apply updates through the WordPress plugin manager.
Workarounds
- Restrict WordPress administrator access to trusted networks using IP allowlisting at the web server or WAF layer.
- Deploy a WordPress-aware Web Application Firewall rule that blocks plugin admin requests missing a valid _wpnonce token.
- Instruct administrators to log out of WordPress before browsing untrusted content and to use a dedicated browser profile for admin tasks.
