CVE-2025-58831 Overview
CVE-2025-58831 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Parallax Scrolling Enllax.js WordPress plugin developed by snagysandor. The flaw impacts all plugin versions up to and including 0.0.6. The vulnerability is classified under CWE-352, which covers missing or improper CSRF protections on state-changing requests.
An attacker can craft a malicious page or link that, when visited by an authenticated WordPress user, triggers unauthorized actions on the target site. Exploitation requires user interaction but no attacker privileges on the target application.
Critical Impact
Successful exploitation allows attackers to forge authenticated requests against WordPress sites running the Parallax Scrolling Enllax.js plugin, potentially altering plugin state or configuration under the victim's session.
Affected Products
- snagysandor Parallax Scrolling Enllax.js plugin for WordPress
- All versions from initial release through 0.0.6
- WordPress installations with the parallax-scrolling-enllax-js plugin enabled

Technical Details for CVE-2025-58831
Vulnerability Analysis
The Parallax Scrolling Enllax.js plugin exposes one or more state-changing endpoints that do not validate a CSRF token or nonce before processing the request. In WordPress, secure request handling typically requires calling wp_verify_nonce() or check_admin_referer() on any handler that modifies plugin settings or performs administrative actions.
Because the plugin omits this validation, the browser of a logged-in administrator will submit a forged request with valid session cookies. The plugin processes the request as if it originated from the legitimate administrator. This mirrors the standard CSRF pattern described under CWE-352.
The impact is limited to integrity, with no direct effect on confidentiality or availability. The EPSS data available at the time of writing indicates a low probability of near-term exploitation, but WordPress plugin CSRF issues are frequently chained with social engineering.
Root Cause
The root cause is the absence of anti-CSRF token verification on plugin request handlers that modify server-side state. WordPress provides a built-in nonce mechanism, but the affected handlers in versions through 0.0.6 do not enforce it. As a result, request origin cannot be validated by the server.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a page containing an auto-submitting form or malicious JavaScript that issues a request to the vulnerable plugin endpoint on the target WordPress site. When a currently authenticated administrator loads the attacker-controlled page, the browser attaches the site's session cookies to the outbound request, and the plugin executes the action.

Detection Methods for CVE-2025-58831
Indicators of Compromise
- Unexpected changes to Parallax Scrolling Enllax.js plugin settings in the WordPress wp_options table.
- Web server access logs showing POST requests to plugin admin endpoints with Referer headers pointing to external domains.
- Administrator sessions submitting plugin configuration changes shortly after visiting untrusted third-party URLs.
Detection Strategies
- Monitor WordPress audit logs for plugin configuration changes that do not correlate with legitimate administrator activity in the admin UI.
- Inspect HTTP request logs for state-changing requests to parallax-scrolling-enllax-js handlers missing a _wpnonce parameter.
- Alert on cross-origin Referer or Origin headers on any authenticated POST request targeting the plugin.
Monitoring Recommendations
- Enable a WordPress activity logging plugin to record settings changes with user, IP, and timestamp attribution.
- Forward web server and WordPress logs to a centralized log analytics platform for correlation with browsing telemetry.
- Review administrator account activity on any workstation observed browsing untrusted content while an active WordPress admin session existed.
How to Mitigate CVE-2025-58831
Immediate Actions Required
- Deactivate the Parallax Scrolling Enllax.js plugin on all WordPress sites until a patched version is available.
- Require administrators to log out of WordPress before browsing untrusted sites, and enforce short session lifetimes.
- Restrict access to the WordPress admin interface using IP allow-listing or a web application firewall (WAF) rule set.
Patch Information
At the time of publication, no fixed version is listed in the Patchstack advisory. All releases through 0.0.6 are affected. Administrators should track the plugin's WordPress repository page for an updated release and apply it as soon as it becomes available.
Workarounds
- Remove or replace the parallax-scrolling-enllax-js plugin with a maintained alternative that enforces WordPress nonces.
- Deploy a WAF rule that blocks POST requests to the plugin's admin endpoints when the Referer or Origin header does not match the site domain.
- Enforce SameSite=Lax or SameSite=Strict cookies for WordPress authentication to reduce cross-site request submission risk.
