AI-suggested

If you cannot patch yet, restrict or monitor authenticated user uploads of SVG or HTML attachments and consider implementing a Content-Security-Policy to mitigate script execution risks.

Description

Teable versions before 2026-10-12T12-45-53Z.3331 contain a stored cross-site scripting (XSS) vulnerability. Authenticated users can upload SVG or HTML attachments with attacker-chosen content types, enabling script execution in the context of the victim's session. This vulnerability allows attackers to perform API actions via the same-origin /api/attachments/read URL, which is served inline with an empty Content-Security-Policy.
