CVE-2025-53269: My Wp Brand Plugin CSRF Vulnerability

CVE-2025-53269 Overview

CVE-2025-53269 is a Cross-Site Request Forgery (CSRF) vulnerability in the imw3 My Wp Brand WordPress plugin (my-wp-brand). The flaw affects all versions up to and including 1.1.3. An attacker can trick an authenticated user into submitting a forged request that performs unintended actions in the plugin. The issue is tracked under CWE-352 and requires user interaction to succeed. Successful exploitation impacts integrity by allowing unauthorized state changes through the victim's browser session.

Critical Impact
An attacker can force an authenticated WordPress user to execute unwanted plugin actions by luring them to a malicious page, resulting in unauthorized modifications to plugin state or branding settings.

Affected Products

imw3 My Wp Brand WordPress plugin
All versions from n/a through 1.1.3
WordPress installations using the my-wp-brand plugin

Technical Details for CVE-2025-53269

Vulnerability Analysis

The my-wp-brand plugin fails to validate the origin of state-changing HTTP requests. WordPress provides nonce tokens through functions such as wp_nonce_field() and check_admin_referer() to prevent CSRF attacks. The vulnerable plugin does not correctly implement or verify these tokens on sensitive endpoints. As a result, any authenticated administrator or privileged user who visits an attacker-controlled page can be forced to submit requests to the WordPress admin interface. The browser automatically attaches valid session cookies, making the request appear legitimate to the server.

Root Cause

The root cause is a missing or improperly validated anti-CSRF token on plugin action handlers, categorized as CWE-352: Cross-Site Request Forgery. The plugin trusts requests based solely on the presence of a valid authentication cookie without confirming user intent through a nonce.

Attack Vector

An attacker crafts a malicious web page or email containing an HTML form or image tag pointing to a vulnerable plugin endpoint. When a logged-in WordPress administrator loads the attacker-controlled content, the browser transmits the forged request with the victim's session cookies. The plugin processes the request as authentic. Exploitation requires user interaction but no prior privileges on the target site. Refer to the Patchstack Vulnerability Report for additional technical detail.

Detection Methods for CVE-2025-53269

Indicators of Compromise

Unexpected changes to WordPress branding, admin UI, or plugin configuration set by my-wp-brand
HTTP POST requests to my-wp-brand handlers with Referer headers pointing to external domains
Administrator activity logs showing configuration changes without corresponding admin panel navigation

Detection Strategies

Inspect web server access logs for requests to plugin action endpoints missing a _wpnonce parameter
Compare Referer and Origin headers on state-changing requests against the WordPress site domain
Correlate authenticated session activity with unusual cross-origin request patterns

Monitoring Recommendations

Enable WordPress audit logging plugins to record administrative configuration changes
Alert on modifications to plugin settings occurring outside standard business hours or from unexpected user agents
Monitor outbound clicks from administrator email accounts to reduce social-engineering exposure

How to Mitigate CVE-2025-53269

Immediate Actions Required

Identify all WordPress sites running the my-wp-brand plugin at version 1.1.3 or earlier
Deactivate the plugin until a patched version is confirmed installed
Require administrators to log out of WordPress sessions before browsing untrusted content

Patch Information

At the time of publication, the vendor advisory referenced by Patchstack lists all versions through 1.1.3 as affected. Site administrators should check the WordPress plugin repository for updates newer than 1.1.3 and apply them immediately. If no patched version is available, remove the plugin.

Workarounds

Deactivate and remove the my-wp-brand plugin until a fixed release is available
Deploy a Web Application Firewall (WAF) rule that blocks POST requests to my-wp-brand endpoints lacking a valid _wpnonce parameter
Restrict WordPress admin access by IP allowlist to limit exposure of authenticated sessions
Educate administrators to avoid clicking untrusted links while logged into WordPress

bash

# Example WAF rule concept to block CSRF attempts against the plugin
# ModSecurity rule blocking cross-origin POSTs to my-wp-brand handlers
SecRule REQUEST_METHOD "@streq POST" \
  "chain,phase:2,deny,status:403,id:1005301,msg:'CSRF attempt on my-wp-brand'"
  SecRule REQUEST_URI "@contains my-wp-brand" \
    "chain"
    SecRule REQUEST_HEADERS:Referer "!@beginsWith https://your-wordpress-site.example/"
