AI Analysis
Technical Summary
CVE-2026-15004 is a stored cross-site scripting vulnerability in the FileBird – WordPress Media Library Folders & File Manager plugin for WordPress. The flaw exists in all versions up to and including 6.5.6, where image alt text is not properly sanitized or escaped before being rendered on web pages. Authenticated attackers with Author-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the injected pages.
Potential Impact
The vulnerability allows an authenticated user with Author-level or higher privileges to inject malicious scripts into pages via image alt text. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation, but does not affect availability. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, and no user interaction required.
Mitigation Recommendations
No official patch or fix is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Author-level access to trusted users only and consider disabling or limiting the use of image alt text inputs. Monitor vendor channels for updates and apply patches promptly once released.
