CVE-2025-53274: WP Permalink Translator CSRF Vulnerability

CVE-2025-53274 Overview

CVE-2025-53274 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP Permalink Translator WordPress plugin developed by Hossin Asaadi. This vulnerability can be chained with a Stored Cross-Site Scripting (XSS) attack, allowing malicious actors to execute arbitrary JavaScript code in the context of authenticated users' browsers.

The vulnerability exists due to missing or improper CSRF token validation in the plugin's administrative functions. An attacker can craft a malicious page that, when visited by an authenticated WordPress administrator, submits unauthorized requests to the vulnerable plugin endpoint. This attack can inject persistent malicious scripts into the WordPress database, which are then executed whenever users view the affected content.

Critical Impact

This CSRF-to-Stored-XSS chain vulnerability allows attackers to compromise WordPress administrator sessions, potentially leading to full site takeover, malware injection, and unauthorized content modification.

Affected Products

• WP Permalink Translator plugin version 1.7.6 and earlier
• WordPress installations with WP Permalink Translator plugin installed
• All WordPress versions running the vulnerable plugin version

Technical Details for CVE-2025-53274

Vulnerability Analysis

This vulnerability combines two distinct attack vectors: Cross-Site Request Forgery (CSRF) and Stored Cross-Site Scripting (XSS). The WP Permalink Translator plugin fails to properly validate CSRF tokens on certain administrative actions, allowing external websites to submit requests on behalf of authenticated administrators.

When an administrator visits a malicious webpage while logged into WordPress, the attacker's page can silently submit requests to the plugin's endpoints. Because the plugin also lacks proper output encoding, these requests can inject malicious JavaScript payloads that persist in the database. Subsequent page loads execute the injected script in the browser context of any user viewing the compromised content.

The attack does not require any user interaction beyond visiting a malicious page while authenticated to WordPress. The stored nature of the XSS component means the malicious payload persists and affects all users who view the infected content.

Root Cause

The root cause of this vulnerability is twofold:

1. Missing CSRF Protection: The plugin does not implement WordPress nonce verification on sensitive administrative functions, allowing cross-origin requests to be processed without authentication of request origin.

2. Insufficient Input Sanitization: User-supplied input is stored in the database without proper sanitization and later rendered on pages without adequate output encoding, enabling persistent script injection.

Attack Vector

The attack follows a multi-stage exploitation chain:

1. The attacker identifies an authenticated WordPress administrator and lures them to a malicious webpage
2. The malicious page contains a hidden form or JavaScript that automatically submits a crafted request to the vulnerable WP Permalink Translator endpoint
3. The request includes malicious JavaScript payload in a parameter that gets stored in the WordPress database
4. When any user (including administrators) views a page where the injected content is displayed, the malicious script executes
5. The script can steal session cookies, create rogue admin accounts, or inject further malicious content

The exploitation mechanism involves crafting HTTP requests that bypass the missing CSRF protection. The attacker's payload typically includes JavaScript designed to exfiltrate administrator credentials or perform privileged actions.

Detection Methods for CVE-2025-53274

Indicators of Compromise

• Unexpected JavaScript code appearing in permalink translations or plugin settings
• Unusual administrator account creations or permission changes without corresponding legitimate activity
• Browser network logs showing requests to unknown external domains from WordPress admin pages
• Modified plugin configuration values containing <script> tags or event handlers

Detection Strategies

• Review WP Permalink Translator settings for any unexpected or suspicious values containing HTML/JavaScript
• Monitor web server access logs for unusual POST requests to plugin endpoints originating from external referrers
• Implement Content Security Policy (CSP) headers to detect and block unauthorized script execution
• Use WordPress security plugins that scan for stored XSS payloads in database content

Monitoring Recommendations

• Enable comprehensive WordPress audit logging to track all administrative changes
• Deploy Web Application Firewall (WAF) rules to detect and block CSRF attack patterns
• Implement real-time monitoring for new user account creation, especially administrator accounts
• Set up alerts for modifications to plugin settings from non-standard referrer sources

How to Mitigate CVE-2025-53274

Immediate Actions Required

• Deactivate the WP Permalink Translator plugin until a patched version is available
• Review all plugin settings and permalink translations for injected malicious content
• Audit WordPress user accounts and remove any unauthorized administrator accounts
• Force password resets for all administrator accounts as a precautionary measure
• Scan the WordPress database for stored XSS payloads using security scanning tools

Patch Information

At the time of publication, users should consult the Patchstack Vulnerability Report for the latest patch status and remediation guidance. Monitor the WordPress plugin repository for updates to WP Permalink Translator beyond version 1.7.6.

Workarounds

• Disable the WP Permalink Translator plugin entirely if not critical to site operations
• Implement strict Content Security Policy headers to mitigate XSS impact: Content-Security-Policy: script-src 'self'
• Use a Web Application Firewall (WAF) to filter malicious requests targeting plugin endpoints
• Restrict WordPress admin access to trusted IP addresses only
• Consider using alternative permalink translation solutions until the vulnerability is patched

# WordPress CLI command to deactivate the vulnerable plugin
wp plugin deactivate wp-permalink-translator

# Check for unauthorized admin accounts
wp user list --role=administrator --format=table

# Add Content Security Policy header in .htaccess (Apache)
# Header set Content-Security-Policy "script-src 'self'; object-src 'none';"
