CVE-2025-23467 Overview
CVE-2025-23467 is a Cross-Site Request Forgery (CSRF) vulnerability in the RSS News Scroller WordPress plugin maintained by vimal.ghorecha. The flaw affects all versions up to and including 2.0.0. An attacker can chain the CSRF weakness with insufficient output encoding to achieve Stored Cross-Site Scripting (XSS) inside the WordPress administrative interface. Successful exploitation requires an authenticated administrator to click an attacker-controlled link or visit a malicious page while logged in. The injected script then persists in the plugin configuration and executes against any user who loads the affected page.
Critical Impact
A successful attack stores JavaScript in the WordPress backend, enabling session theft, administrative account takeover, and persistent site compromise.
Affected Products
- RSS News Scroller WordPress plugin (rss-news-scroller) versions through 2.0.0
- WordPress installations with the plugin active and an authenticated administrator session available
- Sites where administrators browse external content while logged into /wp-admin
Discovery Timeline
- 2025-01-16 - CVE-2025-23467 published to the National Vulnerability Database

Technical Details for CVE-2025-23467
Vulnerability Analysis
The vulnerability combines two distinct weaknesses in the RSS News Scroller plugin. The plugin exposes a settings handler that accepts state-changing requests without verifying a WordPress nonce or other anti-CSRF token, satisfying [CWE-352]. The same handler stores user-supplied input without sufficient sanitization or output encoding, producing a Stored XSS sink. An attacker hosts a page that issues a forged POST request to the plugin's settings endpoint. When an authenticated administrator visits that page, the browser submits the request with valid session cookies. The forged payload writes attacker-controlled markup into plugin configuration, where it later renders inside the WordPress dashboard or front-end view. The injected JavaScript runs with the privileges of any user who loads the affected page, including administrators.
Root Cause
The plugin omits nonce validation on settings updates and fails to apply context-appropriate escaping such as esc_attr() or wp_kses() on stored values. Either control alone would have blocked exploitation.
Attack Vector
Exploitation is network-based and requires user interaction. The attacker delivers a crafted link or auto-submitting form to a logged-in WordPress administrator through phishing, a malicious comment, or a watering-hole page. No credentials or prior access to the target WordPress instance are required.
No verified public proof-of-concept code is available. Technical details are documented in the Patchstack WordPress Vulnerability advisory.
Detection Methods for CVE-2025-23467
Indicators of Compromise
- Unexpected <script>, onerror, or onload attributes stored in the wp_options rows associated with the rss-news-scroller plugin
- Outbound HTTP requests from administrator browsers to unknown domains immediately after loading WordPress admin pages
- Newly created administrator accounts or modified user roles correlated with administrator sessions visiting external sites
Detection Strategies
- Review the plugin's stored settings in the database for HTML or JavaScript content that should contain only plain text values
- Inspect web server access logs for POST requests to wp-admin/admin.php or wp-admin/options.php referencing the rss-news-scroller plugin from external Referer headers
- Hunt for browser-rendered JavaScript that contacts attacker infrastructure when administrators load plugin configuration pages
Monitoring Recommendations
- Enable WordPress audit logging to capture settings changes, user creation, and plugin configuration writes
- Alert on administrator sessions that perform settings changes immediately after navigation from external referrers
- Monitor the rss-news-scroller plugin option keys for changes that include angle brackets, javascript: URIs, or event handler attributes
How to Mitigate CVE-2025-23467
Immediate Actions Required
- Deactivate and remove the RSS News Scroller plugin until a fixed version is published by the maintainer
- Audit plugin settings for injected markup and reset any affected option values to safe defaults
- Rotate WordPress administrator passwords and invalidate active sessions if compromise is suspected
Patch Information
No patched version above 2.0.0 is referenced in the advisory. Site operators should consult the Patchstack advisory for updates from the vendor.
Workarounds
- Remove the plugin entirely if it is not business-critical, since no patched release is documented
- Restrict /wp-admin access using IP allowlists or a VPN to reduce CSRF exposure from administrator browsing
- Deploy a web application firewall rule that requires a valid WordPress nonce parameter on plugin settings endpoints
- Instruct administrators to use a dedicated browser profile for WordPress management and avoid following untrusted links while authenticated
# Configuration example: disable and delete the vulnerable plugin via WP-CLI
wp plugin deactivate rss-news-scroller
wp plugin delete rss-news-scroller
