CVE-2026-54165Network attack vector

Script execution via unsanitized gallery filenames

Published Sep 11, 2026 · Updated Sep 11, 2026

Stored DOM-based XSS in Dobase before 2026.06.03 allows remote authenticated users to run script in public-link visitors' browsers. The public-gallery controller decodes an attacker-controlled filename from a data-name attribute and inserts the raw value into innerHTML without sanitization. Any workspace member permitted to share a Files folder can plant the payload; opening the public link triggers it because the Content-Security-Policy is report-only.
