CVE-2025-31417: WP Docs Authorization Bypass Vulnerability

CVE-2025-31417 Overview

CVE-2025-31417 is a Missing Authorization vulnerability [CWE-862] in the Fahad Mahmood WP Docs plugin for WordPress. The flaw affects all versions of wp-docs from the earliest release through versions prior to 2.2.7. Attackers with low-privilege authenticated access can exploit incorrectly configured access control security levels to perform actions that should be restricted. The vulnerability does not require user interaction and is exploitable over the network. The issue is tracked publicly through Patchstack and impacts the integrity of plugin-managed documentation.

Critical Impact

Authenticated users with low privileges can bypass access control checks in the WP Docs plugin, enabling unauthorized modification of documentation resources.

Affected Products

• Fahad Mahmood WP Docs plugin for WordPress
• All versions from initial release through 2.2.7 (exclusive)
• WordPress sites running wp-docs with default access configuration

Technical Details for CVE-2025-31417

Vulnerability Analysis

The vulnerability is categorized as Missing Authorization [CWE-862]. The WP Docs plugin exposes functionality without properly validating whether the requesting user has permission to invoke it. The plugin relies on incorrectly configured access control security levels, which allow authenticated low-privilege users to reach code paths intended for higher-privileged roles. The scope is limited to integrity impact, meaning attackers can modify plugin-controlled data but cannot directly read confidential information or disrupt availability through this flaw.

Root Cause

The root cause is the absence of a capability check (for example, current_user_can()) on one or more plugin endpoints or AJAX handlers. The plugin treats authentication as sufficient authorization. This breaks the WordPress role-based access model, where plugins must explicitly validate capabilities before performing privileged actions on documents.

Attack Vector

An attacker must first authenticate to the target WordPress site with a low-privilege account such as Subscriber or Contributor. The attacker then issues HTTP requests to the vulnerable plugin endpoint over the network. Because the plugin does not enforce proper authorization, the request succeeds and modifies documentation managed by WP Docs. No user interaction and no elevated privileges are required beyond basic authenticated access.

No verified public proof-of-concept code is available. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2025-31417

Indicators of Compromise

• Unexpected modifications to WP Docs documentation entries by low-privilege user accounts
• WordPress audit log entries showing Subscriber or Contributor accounts invoking WP Docs administrative actions
• HTTP POST requests from authenticated non-admin sessions targeting WP Docs plugin endpoints or AJAX actions

Detection Strategies

• Inventory WordPress installations and identify sites running the wp-docs plugin at versions below 2.2.7
• Review web server access logs for requests to WP Docs endpoints originating from low-privilege session cookies
• Correlate plugin-related database writes with the user role of the authenticated session that issued the request

Monitoring Recommendations

• Enable a WordPress activity logging plugin to capture all document create, update, and delete actions with the invoking user role
• Alert on any WP Docs modification performed by a user whose role is below Editor
• Monitor for anomalous spikes in authenticated requests to /wp-admin/admin-ajax.php referencing WP Docs actions

How to Mitigate CVE-2025-31417

Immediate Actions Required

• Update the WP Docs plugin to a version later than 2.2.7 where the authorization check is enforced
• Audit existing WP Docs content for unauthorized modifications introduced by low-privilege accounts
• Review the roles and capabilities assigned to all registered WordPress users and remove unnecessary accounts

Patch Information

The vendor addressed the issue in WP Docs releases after 2.2.7. Site administrators should upgrade via the WordPress plugin manager. Validate the upgrade by confirming the installed plugin version and reviewing the Patchstack Vulnerability Report for the fixed version number.

Workarounds

• Deactivate the WP Docs plugin until the patched version can be installed
• Restrict new user registration or disable the Subscriber role on sites where WP Docs is deployed
• Place a Web Application Firewall (WAF) rule in front of WordPress that blocks non-administrator sessions from reaching WP Docs plugin endpoints

# Verify installed WP Docs plugin version using WP-CLI
wp plugin get wp-docs --field=version

# Update WP Docs to the latest patched release
wp plugin update wp-docs

# As a temporary workaround, deactivate the plugin
wp plugin deactivate wp-docs
