AI Analysis
Technical Summary
The Elementor Header & Footer Builder plugin for WordPress, part of brainstormforce's Ultimate Addons for Elementor, suffers from a stored XSS vulnerability (CWE-87) due to insufficient input sanitization and output escaping of the 'size' attribute. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript code that executes in the context of users visiting the compromised pages. This vulnerability affects all versions up to 1.6.26 and has a CVSS 3.1 base score of 6.4 (medium severity). No patch or remediation details are currently available, and no active exploitation has been reported.
Potential Impact
Successful exploitation allows an authenticated user with contributor or higher privileges to inject persistent malicious scripts into pages. These scripts execute in the browsers of users who view the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not impact availability but can compromise confidentiality and integrity of user sessions and data.
Mitigation Recommendations
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 affected plugin. Monitor for updates from brainstormforce regarding patches or official mitigations.
