CVE-2025-58670: WP Content Protection CSRF Vulnerability

CVE-2025-58670 Overview

CVE-2025-58670 is a Cross-Site Request Forgery (CSRF) vulnerability in the Shankaranand Maurya WP Content Protection plugin for WordPress. The flaw affects all versions up to and including 1.3. An attacker can leverage the CSRF weakness to inject persistent JavaScript into the plugin's configuration, resulting in Stored Cross-Site Scripting (XSS) when an administrator visits the affected page. Exploitation requires user interaction, typically through a crafted link or page loaded by an authenticated administrator. The issue is tracked under CWE-352: Cross-Site Request Forgery.

Critical Impact
Successful exploitation chains CSRF with Stored XSS, allowing attackers to execute arbitrary script in administrator browsers and pivot toward full site takeover.

Affected Products

Shankaranand Maurya WP Content Protection plugin for WordPress
All versions from n/a through <= 1.3

Technical Details for CVE-2025-58670

Vulnerability Analysis

The vulnerability combines two web application weaknesses: CSRF and Stored XSS. The plugin's administrative actions lack proper anti-CSRF tokens, allowing forged requests to be processed as legitimate. When an authenticated administrator is tricked into visiting an attacker-controlled page, the browser silently submits a request that updates plugin settings. Because the submitted data is stored and later rendered without adequate output encoding, the injected payload executes as JavaScript in the administrator's session context.

The attack scales the impact beyond a typical CSRF because the malicious payload persists in the database. Every subsequent administrator who loads the affected page triggers the script, expanding the blast radius. Common follow-on actions include creating rogue administrator accounts, exfiltrating session cookies, and modifying plugin or theme files to establish persistence.

Root Cause

The root cause is the absence of WordPress nonce verification on state-changing requests handled by the plugin. WordPress provides wp_nonce_field() and check_admin_referer() to mitigate CSRF, but the affected plugin code paths do not validate these tokens. The secondary defect is insufficient sanitization and escaping of stored input, which permits HTML and script content to be rendered verbatim in administrative pages.

Attack Vector

The vulnerability is exploitable over the network and requires user interaction from a privileged user. An attacker hosts a page containing an auto-submitting form or an <img>/<script> element that triggers an authenticated request to the WordPress administrator's site. Once the forged request lands, the stored payload activates on the next administrator page load. No credentials are required by the attacker, who relies entirely on the victim's authenticated session.

The vulnerability is described in prose only because no verified public proof-of-concept code is available. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-58670

Indicators of Compromise

Unexpected <script>, <iframe>, or event-handler attributes stored in plugin option records within wp_options or related plugin tables.
HTTP POST requests to plugin administrative endpoints with Referer headers pointing to external or unrelated domains.
Creation of new WordPress administrator accounts immediately following an admin session with the plugin settings page.
Outbound requests from the WordPress server or admin browsers to unfamiliar domains shortly after settings changes.

Detection Strategies

Audit the wp-content-protection plugin's stored settings for HTML or JavaScript content that should not appear in configuration fields.
Monitor WordPress audit logs for plugin setting modifications that occur without a corresponding administrator navigation to the settings UI.
Compare web server access logs against admin activity to identify settings updates initiated from external referrers.

Monitoring Recommendations

Enable a WordPress activity logging plugin to record changes to plugin options and user accounts.
Implement a Content Security Policy (CSP) for /wp-admin/ to surface unexpected inline script execution.
Forward WordPress and web server logs to a centralized analytics platform for correlation of CSRF and XSS indicators.

How to Mitigate CVE-2025-58670

Immediate Actions Required

Deactivate and remove the WP Content Protection plugin until a patched version is confirmed available from the vendor.
Rotate WordPress administrator passwords and invalidate all active sessions after removing the plugin.
Review the wp_users table for unauthorized accounts and the wp_options table for injected script content.
Inspect themes, mu-plugins, and wp-content/uploads for backdoors that may have been planted via XSS-driven actions.

Patch Information

At the time of publication, no fixed version is identified in the available advisory data. Monitor the Patchstack advisory for updates from the plugin maintainer and apply any released patch immediately. Versions through 1.3 are confirmed vulnerable.

Workarounds

Restrict access to /wp-admin/ by IP allowlisting at the web server or WAF layer to reduce CSRF exposure.
Require administrators to use a dedicated browser profile for WordPress administration to limit cross-site request leakage.
Deploy a WordPress-aware Web Application Firewall ruleset that enforces nonce validation and blocks script payloads in plugin option updates.

bash

# Example: temporarily disable the vulnerable plugin via WP-CLI
wp plugin deactivate wp-content-protection
wp plugin delete wp-content-protection

# Audit stored options for suspicious script content
wp option list --search='*wp_content_protection*' --format=table
