CVE-2026-18749

Broken access control

9.8 CRITICALEPSS 0.51%
  1. Published12 Aug 2026

Description

The type=track branch authorises on _is_my_case(t_attach.case) only and never checks VinceTrackAttachment.shared. A coordinator-uploaded case artefact that has NOT been marked shared is still retrievable by any case member who has (or is sent) its uuid — leaks not-yet-released coordinator material to vendors on the case.
