Cross-Site Scripting (XSS) in Dobase (CVE-2026-54165)
Summary
Cross-site scripting in Dobase (CVE-2026-54165). Risk of unauthorized operations or information disclosure. Exploitable via name.
Original description
The description as published by the source.
Dobase is an open-source, self-hosted workspace with installable tools. Versions prior to 2026.06.03 have a one-click stored DOM-based cross-site scripting (XSS) vulnerability in the public, unauthenticated shared-folder image gallery. A file's name is fully attacker-controlled and is never sanitized. It is round-tripped through an ERB-escaped data-name attribute, decoded back to its raw value by el.dataset.name, and then re-injected into innerHTML by the public-gallery Stimulus controller with no escaping. Any authenticated workspace member who can share a Files folder can store a payload; the victim is anyone with the public share link (no authentication required). The global Content-Security-Policy is sent report-only (not enforcing), so an inline onerror handler executes — this is an executing XSS, not a CSP-mitigated injection. Version 2026.06.03 fixes the issue.
