CVE-2025-52780: Samandehi Logo Manager CSRF Vulnerability

CVE-2025-52780 Overview

CVE-2025-52780 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Logo Manager For Samandehi WordPress plugin developed by Mohammad Parsa. This vulnerability allows attackers to chain CSRF with Stored Cross-Site Scripting (XSS) attacks, enabling malicious actors to inject persistent scripts into the affected WordPress sites by tricking authenticated administrators into performing unintended actions.

Critical Impact

Attackers can exploit this CSRF vulnerability to inject malicious JavaScript that persists in the WordPress database, potentially compromising all site visitors and administrators who view the affected pages.

Affected Products

• Logo Manager For Samandehi WordPress Plugin version 0.5 and earlier
• WordPress sites running the samandehi-logo-manager plugin

Technical Details for CVE-2025-52780

Vulnerability Analysis

This vulnerability combines two distinct attack vectors: Cross-Site Request Forgery (CWE-352) and Stored Cross-Site Scripting. The Logo Manager For Samandehi plugin fails to implement proper CSRF token validation on sensitive administrative actions, allowing attackers to craft malicious requests that execute in the context of authenticated administrators.

When an administrator visits a malicious page while logged into WordPress, the attacker-controlled page can submit forged requests to the plugin's administrative endpoints. Because the plugin does not validate CSRF tokens, these requests are processed as legitimate administrative actions. The secondary impact is Stored XSS, where malicious JavaScript payloads can be injected and stored in the database, executing whenever users view the affected content.

Root Cause

The root cause of this vulnerability is the absence of nonce verification in the plugin's form handling logic. WordPress provides built-in CSRF protection through its nonce system (wp_nonce_field() and wp_verify_nonce()), but the Logo Manager For Samandehi plugin fails to implement these security controls on its administrative forms. Additionally, the plugin does not properly sanitize or escape user-supplied input before storing it in the database, enabling the Stored XSS component of this attack chain.

Attack Vector

The attack requires social engineering to trick an authenticated WordPress administrator into visiting a malicious webpage. The attacker crafts an HTML page containing a hidden form that submits a request to the vulnerable plugin endpoint. This form includes malicious JavaScript payload in the input fields.

When the administrator visits the attacker's page, JavaScript automatically submits the hidden form, or the attacker may use CSS to disguise a submit button as legitimate content. Since the administrator's browser includes their WordPress authentication cookies with the request, and the plugin lacks CSRF protection, the malicious payload is accepted and stored.

The Stored XSS payload then executes whenever any user or administrator views the page containing the logo manager output, potentially leading to session hijacking, administrative account compromise, or further malware distribution.

Detection Methods for CVE-2025-52780

Indicators of Compromise

• Unexpected JavaScript or HTML content in logo manager plugin settings or database entries
• Suspicious <script> tags or event handlers (e.g., onerror, onload) in plugin configuration data
• Unusual outbound network requests from WordPress pages to unknown external domains
• Browser console errors indicating blocked cross-origin requests from injected scripts

Detection Strategies

• Review WordPress database tables associated with the samandehi-logo-manager plugin for unexpected HTML or JavaScript content
• Monitor web server access logs for POST requests to plugin endpoints originating from external referrers
• Implement Content Security Policy (CSP) headers to detect and block unauthorized inline script execution
• Use WordPress security plugins to scan for known malicious patterns in stored content

Monitoring Recommendations

• Enable WordPress audit logging to track changes made through the plugin's administrative interface
• Configure web application firewall (WAF) rules to alert on suspicious patterns in POST request bodies
• Monitor for anomalous administrative activity, particularly bulk configuration changes without corresponding administrator logins

How to Mitigate CVE-2025-52780

Immediate Actions Required

• Disable or deactivate the Logo Manager For Samandehi plugin until a patched version is available
• Review and sanitize any existing content stored by the plugin for malicious scripts
• Implement additional WordPress security hardening measures including strict Content Security Policy headers
• Educate WordPress administrators about the risks of clicking links while authenticated to the dashboard

Patch Information

At the time of writing, administrators should consult the Patchstack Vulnerability Report for the latest patch status and remediation guidance. Version 0.5 and all prior versions are confirmed vulnerable.

Workarounds

• Completely remove the samandehi-logo-manager plugin if it is not essential to site functionality
• Restrict WordPress administrative access to trusted IP addresses only using .htaccess or firewall rules
• Implement a Web Application Firewall (WAF) with CSRF protection rules to filter malicious requests
• Use browser extensions or policies that prevent automatic form submission on external sites

# Example: Restrict WordPress admin access by IP in .htaccess
# Add to .htaccess in wp-admin directory
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
    RewriteCond %{REMOTE_ADDR} !^10\.0\.0\.50$
    RewriteRule .* - [F,L]
</IfModule>
