The Supreme Addons for Beaver Builder WordPress plugin contains a stored XSS vulnerability (CWE-79) in the auto_qrcodesabb shortcode due to improper neutralization of user-supplied input. Authenticated users with contributor-level privileges or above can inject arbitrary web scripts that persist and execute in the context of other users visiting the compromised pages. This vulnerability affects all plugin versions up to 1.0.9. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact without availability impact. No patch or vendor advisory is currently provided.

An attacker with contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. This can lead to unauthorized script execution in the context of users viewing those pages, potentially compromising user data confidentiality and integrity. There is no indication of impact on system availability. No known exploits in the wild have 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 removing the affected shortcode if possible. Monitor official sources for updates and apply patches promptly once available.
