## Overview

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.
