CVE-2024-7453Public exploitNetwork attack vector

Stored XSS via unsanitized attachment metadata

Published Aug 4, 2024 · Updated Aug 5, 2024

Stored XSS in FastAdmin 1.5.0.20240328 Attachment Management allows remote authenticated users to execute script in an administrator's browser. The attachment edit handler stores row[url], row[imagewidth], and row[imageheight] values without neutralizing HTML, and the backend later renders them into an attachment view. Attachment-management privileges are required to plant the payload, and execution requires a higher-privileged administrator to view or edit the record.
