CVE-2025-58202: Simple Page Access Restriction CSRF Flaw

CVE-2025-58202 Overview

CVE-2025-58202 is a Cross-Site Request Forgery (CSRF) vulnerability in the Simple Page Access Restriction WordPress plugin by Plugins and Snippets. The flaw affects all versions up to and including 1.0.32. Attackers can trick authenticated users into submitting unwanted state-changing requests through crafted links or embedded content. Successful exploitation requires user interaction, typically clicking a malicious link while logged in. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery and is documented in the Patchstack WordPress Vulnerability Report.

Critical Impact
Attackers can perform unauthorized state-changing actions on behalf of authenticated WordPress users, potentially altering page access restrictions configured by the plugin.

Technical Details for CVE-2025-58202

Vulnerability Analysis

The Simple Page Access Restriction plugin exposes actions that change plugin state without validating that a request originated from an intended user session. The plugin lacks proper anti-CSRF token verification on sensitive endpoints. An attacker can craft an HTML page or link that, when visited by a logged-in WordPress administrator, submits requests to the vulnerable plugin endpoints. The browser attaches the victim's authentication cookies automatically, causing the request to execute with the victim's privileges.

Exploitation requires user interaction, which limits automated abuse. However, targeted phishing campaigns against WordPress administrators can reliably deliver the malicious link. The impact is limited to integrity of plugin-managed data, with no direct confidentiality or availability effect according to the CVSS vector.

Root Cause

The root cause is missing or improperly implemented CSRF protection on plugin actions. WordPress provides nonce functions such as wp_nonce_field() and check_admin_referer() for this purpose. When these safeguards are absent from form submissions or admin-post handlers, any authenticated request originating from a cross-site context is accepted as legitimate.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker hosts a page containing a hidden form or JavaScript that auto-submits a request to the target WordPress site. A signed-in administrator who visits the attacker-controlled page triggers the forged request, modifying plugin configuration or page access rules without consent.

No verified public exploit code is available. Refer to the Patchstack advisory for further technical context.

Detection Methods for CVE-2025-58202

Indicators of Compromise

Unexpected changes to page access restrictions or plugin settings without a corresponding administrator action in audit logs.
HTTP POST requests to plugin admin endpoints containing external Referer headers pointing to untrusted domains.
Administrator sessions performing configuration changes shortly after browsing external links or opening email attachments.

Detection Strategies

Inspect web server access logs for state-changing requests to /wp-admin/admin-post.php or plugin-specific endpoints lacking a _wpnonce parameter.
Correlate WordPress audit plugin events with browser referrer data to identify cross-origin submission patterns.
Deploy a Web Application Firewall (WAF) rule that flags POST requests to the plugin without a valid nonce token.

Monitoring Recommendations

Enable WordPress activity logging to capture user, IP, referrer, and timestamp for every settings change.
Monitor for anomalous administrator behavior, such as configuration changes originating from unusual geolocations or user agents.
Alert on modifications to the simple-page-access-restriction plugin options table entries.

How to Mitigate CVE-2025-58202

Immediate Actions Required

Update the Simple Page Access Restriction plugin to a version above 1.0.32 once the vendor publishes a patched release.
Restrict WordPress administrator accounts to dedicated browsing sessions and avoid clicking external links while authenticated.
Audit current plugin configuration to confirm access restrictions have not been tampered with.

Patch Information

At the time of publication, no fixed version above 1.0.32 is referenced in the advisory data. Monitor the Patchstack advisory and the plugin's WordPress.org page for a patched release.

Workarounds

Deactivate and remove the Simple Page Access Restriction plugin until a patched version is available.
Deploy a WAF ruleset that requires a valid _wpnonce parameter on all requests to plugin admin endpoints.
Enforce short administrator session lifetimes and require re-authentication for sensitive configuration changes.
Use browser isolation or a dedicated browser profile for WordPress administration to limit cross-site request exposure.
