CVE-2025-57937 Overview
CVE-2025-57937 is a sensitive data exposure vulnerability in the WPeMatico RSS Feed Fetcher plugin for WordPress, developed by etruel. The flaw affects all plugin versions up to and including 2.8.10. An authenticated attacker with low privileges can retrieve embedded sensitive system information that should remain restricted. The weakness is classified under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere.
Critical Impact
Low-privileged authenticated users can read sensitive data embedded in the plugin, which may aid reconnaissance and follow-on attacks against the WordPress environment.
Affected Products
- etruel WPeMatico RSS Feed Fetcher plugin for WordPress
- All versions from initial release through 2.8.10
- WordPress sites running the vulnerable plugin with authenticated low-privileged users

Technical Details for CVE-2025-57937
Vulnerability Analysis
The WPeMatico RSS Feed Fetcher plugin exposes sensitive system information to users who should not have access to it. The plugin fails to enforce an appropriate authorization boundary around data that includes system or configuration details. An attacker who holds a low-privileged account on the WordPress site can issue a request over the network and retrieve the embedded data. The confidentiality impact is limited to information disclosure; integrity and availability are not affected.
Root Cause
The root cause is improper access control around resources that embed sensitive system information. The plugin places this data within a control sphere accessible to authenticated users without validating that the requesting principal is authorized. This pattern aligns with CWE-497, where sensitive internals are exposed to an unauthorized control sphere.
Attack Vector
Exploitation requires network access to the WordPress site and valid credentials for a low-privileged account such as subscriber or contributor. No user interaction is required beyond the attacker's own authenticated request. The attacker invokes the vulnerable plugin endpoint and parses the response for the embedded sensitive data. Further technical details are available in the Patchstack advisory.
No public proof-of-concept exploit code is available in the referenced sources. The vulnerability mechanism is described above in prose because no verified exploit code has been published.
Detection Methods for CVE-2025-57937
Indicators of Compromise
- Unexpected authenticated HTTP requests to WPeMatico plugin endpoints under /wp-admin/admin-ajax.php or /wp-content/plugins/wpematico/ from low-privileged accounts
- Response payloads containing system configuration strings, file paths, or feed-processing internals delivered to non-administrator sessions
- Repeated enumeration patterns from a single authenticated session targeting plugin resources
Detection Strategies
- Review WordPress access logs for requests to WPeMatico plugin URLs originating from accounts with roles below editor
- Correlate newly created low-privileged accounts with subsequent requests to plugin administrative endpoints
- Compare installed plugin version against the fixed release and flag any instance at or below 2.8.10
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward web server access logs to a centralized analytics platform
- Alert on anomalous volumes of admin-ajax.php requests tied to WPeMatico action parameters
- Monitor for registration spikes of low-privileged users followed by plugin endpoint access
How to Mitigate CVE-2025-57937
Immediate Actions Required
- Inventory all WordPress deployments and identify instances running WPeMatico RSS Feed Fetcher at version 2.8.10 or earlier
- Update the plugin to a version later than 2.8.10 once released by the vendor
- Audit existing low-privileged WordPress accounts and remove unused or unknown users
- Restrict new user registration to trusted workflows until the plugin is patched
Patch Information
Refer to the Patchstack advisory for WPeMatico for current patch status. Apply the vendor-supplied update as soon as it is published. Verify the plugin version after update by checking the WordPress admin plugins page.
Workarounds
- Deactivate the WPeMatico RSS Feed Fetcher plugin until a fixed version is installed
- Apply a Web Application Firewall rule to block requests to WPeMatico endpoints from non-administrator sessions
- Disable open user registration (Settings > General > Membership) to reduce the pool of low-privileged accounts available to attackers
# Disable WPeMatico via WP-CLI until a patched version is available
wp plugin deactivate wpematico
# Verify installed version across managed sites
wp plugin get wpematico --field=version
