CVE-2026-73350Network attack vector

Unauthenticated access via broken authentication

Published Aug 18, 2026 · Updated Aug 18, 2026

Broken authentication in PSM Plugins SupportCandy before 3.5.2 allows remote attackers to access plugin data and functions without logging in. Patchstack characterizes the bug as incorrect privilege assignment in authentication handling, but public records do not disclose the vulnerable endpoint, parameter, or code path. The issue is network-reachable with no authentication or user interaction, and published scoring bounds the impact to unauthorized access to SupportCandy data and some privileged actions rather than code execution or service interruption.
