CVE-2026-6292MP Customize Login Page <= 1.0 - Cross-Site Request Forgery to Settings Update
Medium 4.3
In plain English
A medium-severity cross-site request forgery in MP Customize Login Page from manuelpadillac. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 18% of all known vulnerabilities).
Official description
The MP Customize Login Page plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to and including 1.0. This is due to a completely broken nonce validation in the enter_mpclp_login_options() function, which contains an inverted check (if wp_verify_nonce(...) { return false; }) and is missing the required action parameter for wp_verify_nonce(). As a result, the nonce check is effectively dead code: it never blocks malicious requests because a CSRF-supplied empty/invalid nonce always returns false, satisfying the inverted condition to continue execution. Furthermore, the settings-update handler is hooked on init without any capability check. This makes it possible for unauthenticated attackers to modify all plugin setting, including login page background, logo URL, image dimensions, button colors, and login message, by tricking a logged-in administrator into submitting a crafted request.
