CVE-2026-56781Public exploitNetwork attack vector

Unauthenticated hidden-field disclosure via projection override

Published Jun 29, 2026 · Updated Jun 29, 2026

Improper access control in Teable before 2026-06-15T04-43-24Z.1912 allows remote attackers to read hidden fields through a shared view. The share-view records path accepts a client projection instead of intersecting it with the view's allowed fields, while anonymous metadata exposes hidden field IDs. A valid public share link is required; exposure is limited to field values in that shared view and does not enable writes.
