CyberRota Analysis

AI-Generated

Dobase versions prior to 2026.06.03 are vulnerable to a stored DOM-based cross-site scripting (XSS) attack via the public, unauthenticated shared-folder image gallery, where an attacker can exploit the unsanitized `name` attribute of a file. This vulnerability allows any authenticated user who can share a folder to inject malicious payloads, impacting anyone with access to the public share link. Organizations using Dobase should prioritize upgrading to version 2026.06.03 to mitigate the risk of XSS attacks.

Original NVD Description

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.
