CVE-2024-11118Network attack vector

Plugin settings modification via missing nonce validation

Published Nov 16, 2024 · Updated Apr 8, 2026

Cross-site request forgery in Bilbud 404 Error Monitor 1.1 and earlier allows remote attackers to modify plugin settings via forged requests. The updatePluginSettings() function accepts state-changing requests without correctly validating a WordPress nonce, enabling settings updates and deletion of stored error logs. Exploitation requires a logged-in site administrator to perform an attacker-induced action, such as following a crafted link; no broader data or code-execution impact is reported.
