CVE-2025-53261 Overview
CVE-2025-53261 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP YouTube Live plugin (wp-youtube-live) for WordPress, developed by macbookandrew. The issue affects all plugin versions up to and including 1.10.0. An attacker can trick an authenticated WordPress user into submitting a forged request that performs unintended state-changing actions on the site. Exploitation requires user interaction, typically through a malicious link or embedded content. The flaw is tracked under CWE-352: Cross-Site Request Forgery.
Critical Impact
A remote attacker can perform unauthorized actions in the context of an authenticated user, resulting in limited integrity impact on the affected WordPress site.
Affected Products
- macbookandrew WP YouTube Live plugin for WordPress
- All versions from n/a through 1.10.0
- WordPress installations using wp-youtube-live

Technical Details for CVE-2025-53261
Vulnerability Analysis
The WP YouTube Live plugin fails to implement adequate anti-CSRF protections on one or more state-changing request handlers. WordPress provides the wp_nonce_field() and check_admin_referer() primitives specifically to defend against forged requests, but the affected code paths do not validate a nonce or verify the origin of the request. As a result, an attacker-controlled page can issue cross-origin requests that the victim's browser will submit with valid authentication cookies. The plugin processes those requests as though they came from a legitimate administrative action.
The attack requires the victim to visit a malicious page while authenticated to the target WordPress site. The impact is limited to integrity — the vulnerability does not directly expose confidential data or degrade availability of the site.
Root Cause
The root cause is the absence of CSRF token validation on privileged request handlers within wp-youtube-live. Without a per-session nonce, the plugin cannot distinguish between a request initiated by a legitimate administrator interaction and a forged request submitted by a third-party site. This is the classic condition described in CWE-352.
Attack Vector
Exploitation proceeds over the network and requires user interaction. An attacker crafts an HTML page containing an auto-submitting form or image tag that targets a vulnerable plugin endpoint on the victim's WordPress site. When an authenticated user with sufficient privileges visits the attacker's page, the browser submits the request with the user's session cookies, and the plugin executes the state-changing action. No stored credentials are exposed and no code execution is achieved through this flaw alone.
Because no verified proof-of-concept has been published, the specific vulnerable endpoint and parameters are documented in the Patchstack WordPress Vulnerability advisory.
Detection Methods for CVE-2025-53261
Indicators of Compromise
- Unexpected configuration changes to WP YouTube Live plugin settings without a corresponding admin session.
- HTTP POST or GET requests to wp-youtube-live endpoints with Referer or Origin headers pointing to unrelated third-party domains.
- Administrative actions logged from users whose browser session originated on external sites.
Detection Strategies
- Review web server access logs for requests to plugin endpoints missing a WordPress nonce parameter (typically _wpnonce).
- Correlate WordPress audit logs with authenticated user browsing activity to identify state changes that lack a direct admin-panel referrer.
- Deploy a Web Application Firewall (WAF) rule set that flags cross-origin state-changing requests to WordPress plugin routes.
Monitoring Recommendations
- Enable a WordPress activity logging plugin to record all administrative actions with user, IP, and referrer metadata.
- Alert on modifications to plugin configuration outside change windows.
- Monitor for external referrers on any admin-ajax.php or plugin AJAX action calls tied to wp-youtube-live.
How to Mitigate CVE-2025-53261
Immediate Actions Required
- Identify all WordPress sites running the WP YouTube Live plugin at version 1.10.0 or earlier.
- Deactivate the wp-youtube-live plugin until a fixed version is confirmed installed.
- Force logout of all administrative sessions and rotate any credentials that may have been used on compromised browsers.
- Audit plugin settings and recent content changes for signs of unauthorized modification.
Patch Information
At the time of publication, the vendor advisory tracked by Patchstack covers versions up to and including 1.10.0. Administrators should upgrade to any release later than 1.10.0 once the maintainer publishes a fixed build, and confirm the changelog references CSRF protection or nonce validation.
Workarounds
- Remove or deactivate the WP YouTube Live plugin until a patched release is verified.
- Restrict WordPress administrative access to trusted IP addresses using web server ACLs or a WAF.
- Require administrators to use a dedicated browser profile for WordPress management to reduce the chance of visiting attacker-controlled pages while authenticated.
- Enforce the SameSite=Lax or SameSite=Strict attribute on WordPress session cookies where compatible.
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate wp-youtube-live
wp plugin status wp-youtube-live
