CVE-2025-54042 Overview
CVE-2025-54042 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Xfinitysoft WP Post Hide WordPress plugin. The issue impacts all versions of wp-post-hide up to and including 1.0.9. The flaw is categorized under [CWE-352] and allows an attacker to trigger unauthorized state-changing actions when an authenticated WordPress user visits an attacker-controlled page.
The vulnerability requires user interaction and can be exploited over the network without prior authentication by the attacker. Successful exploitation results in limited integrity impact on the WordPress site.
Critical Impact
An attacker can trick authenticated WordPress administrators into executing unintended actions on the WP Post Hide plugin, resulting in unauthorized modifications to post visibility settings.
Affected Products
- Xfinitysoft WP Post Hide plugin for WordPress
- All versions from n/a through 1.0.9
- WordPress sites with wp-post-hide installed and active

Technical Details for CVE-2025-54042
Vulnerability Analysis
CVE-2025-54042 stems from missing or improperly implemented anti-CSRF protections in the WP Post Hide plugin. The plugin fails to validate WordPress nonces on state-changing requests. This allows a remote attacker to craft malicious HTML or JavaScript payloads that submit forged requests on behalf of an authenticated administrator.
When a logged-in WordPress user visits a malicious page, the browser automatically includes the user's authentication cookies with requests to the vulnerable endpoint. The plugin processes these requests as if they originated from the legitimate user. The attacker never sees the response but achieves modifications through the victim's session context.
The issue is limited to integrity impact. Confidentiality and availability are not directly affected by exploitation, per the CVSS vector reported for this issue.
Root Cause
The root cause is the absence of proper CSRF token verification within request handlers exposed by the wp-post-hide plugin. WordPress provides wp_nonce_field() and check_admin_referer() primitives for this purpose. The plugin does not correctly apply these controls to sensitive actions, leaving them accessible via forged cross-origin requests.
Attack Vector
Exploitation requires an authenticated WordPress user, typically an administrator, to interact with attacker-controlled content. The attacker hosts a page containing an auto-submitting form or fetch request targeting the vulnerable plugin endpoint on the victim's WordPress site. Upon visit, the victim's browser submits the request with valid session cookies, and the plugin executes the action.
No exploit is publicly available at this time, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Patchstack WordPress Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-54042
Indicators of Compromise
- Unexpected changes to post visibility settings managed by the WP Post Hide plugin
- WordPress access logs showing state-changing requests to wp-post-hide endpoints originating from external Referer headers
- Administrator sessions performing plugin actions immediately after visiting external sites
Detection Strategies
- Review WordPress audit logs for plugin configuration changes lacking a corresponding admin UI navigation trail
- Inspect HTTP request logs for POST or GET requests to wp-post-hide handlers with off-domain or missing Referer values
- Correlate administrator browsing activity with plugin state changes to identify forged actions
Monitoring Recommendations
- Enable a WordPress activity logging plugin to record all plugin setting modifications with user attribution
- Monitor web server logs for requests to admin-ajax.php and plugin-specific endpoints missing valid nonce parameters
- Alert on administrator account activity that occurs outside expected working hours or from unusual client contexts
How to Mitigate CVE-2025-54042
Immediate Actions Required
- Deactivate the WP Post Hide plugin until a patched version is available if it is not business-critical
- Restrict WordPress administrator accounts from browsing untrusted sites while authenticated to the WordPress admin panel
- Enforce short session lifetimes and require re-authentication for sensitive administrative actions
Patch Information
At the time of publication, no fixed version of the WP Post Hide plugin is listed. Versions through 1.0.9 remain affected. Monitor the Patchstack advisory and the plugin's WordPress.org listing for updates.
Workarounds
- Remove or disable the wp-post-hide plugin until the vendor releases a fix that validates WordPress nonces on all state-changing requests
- Deploy a web application firewall rule to block cross-origin POST requests to plugin endpoints lacking a valid Referer matching the WordPress site
- Require administrators to use isolated browsers or profiles dedicated to WordPress administration to reduce CSRF exposure
# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate wp-post-hide
wp plugin delete wp-post-hide
