The Master Addons for Elementor plugin (versions up to 2.0.6.7) contains a stored cross-site scripting vulnerability (CWE-79) in its Tooltip module. This vulnerability allows authenticated users with contributor-level privileges or higher to inject arbitrary JavaScript code into pages via insufficient sanitization and escaping of input attributes. When other users visit these pages, the injected scripts execute in their browsers, potentially leading to session hijacking or other client-side attacks. The vulnerability has a CVSS 3.1 score of 6.4, reflecting network attack vector, low attack complexity, and limited privileges required. No patch or remediation guidance is currently available from the vendor or advisory data.

An attacker with contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into web pages generated by the plugin. These scripts execute in the context of users visiting the affected pages, potentially leading to theft of user credentials, session tokens, or other sensitive information accessible via the browser. The vulnerability does not impact availability but compromises confidentiality and integrity of user sessions. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Tooltip module in the Master Addons plugin. Monitor for plugin updates from litonice13 and apply them promptly once available.
