Technical details

The shareLoader fails to verify unpublished status when loading shared documents, allowing unauthenticated users with an existing share link to access withdrawn content via shares.info, documents.info, or /s/ share routes. An attacker holding a share link can bypass publication checks, while the shares.revoke endpoint incorrectly returns 404, preventing proper revocation of compromised links.
