AI Analysis
Technical Summary
The Beaver Builder Page Builder plugin for WordPress contains a stored XSS vulnerability (CWE-79) in its Button Group module due to improper neutralization of input during web page generation. Authenticated attackers with contributor-level privileges or above can inject arbitrary JavaScript code via insufficiently sanitized user input. This malicious code executes in the context of users who visit the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 2.8.3.6 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).
Potential Impact
An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the Button Group module. These scripts execute in the browsers of users who view the infected pages, potentially leading to information disclosure or manipulation of user interactions. The vulnerability does not allow denial of service or elevation of privileges beyond the existing contributor-level access but can compromise confidentiality and integrity of user sessions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Button Group module. Monitor for plugin updates from Beaver Builder and apply official patches promptly once released.
