The Master Addons for Elementor plugin suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input in the Pricing Table widget. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of other users viewing the affected pages. This vulnerability impacts all plugin versions up to 2.0.5.6. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and partial impact on confidentiality and integrity but no impact on availability. No patch or official fix information is currently available.

Successful exploitation allows an attacker with contributor-level access to inject persistent malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to partial confidentiality and integrity compromise, such as session hijacking or unauthorized actions performed in the context of affected users. There is no impact on system availability. 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 removing or disabling the Pricing Table widget if feasible. Monitor for updates from the plugin vendor and apply patches promptly once available.
