CVE-2026-120114 Details
Description
The Debug Log Manager – Conveniently Monitor and Inspect Errors plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'message (and pageUrl)' parameter in all versions up to, and including, 2.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the site administrator has debug logging enabled with JS error logging active, and that the attacker can obtain the publicly emitted dlmVars.jsErrorLogging nonce — which is broadcast on every frontend page — to pass the nonce check on the unauthenticated endpoint.
A stored cross-site scripting vulnerability has been identified in the Debug Log Manager plugin for WordPress, affecting all versions through 2.5.2. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when users access the compromised page. Exploitation requires the site administrator to have debug logging enabled, with JavaScript error logging active. Additionally, the attacker must obtain the publicly available 'dlmVars.jsErrorLogging' nonce, which is transmitted on every frontend page, to bypass the nonce check on the unauthenticated endpoint.
Users are advised to update the Debug Log Manager plugin to version 2.5.3 or a newer patched version.
