CVE-2026-42303
Fides: Privacy Request Identity Verification Bypass Vulnerability via Duplicate Detection
Description
Fides is an open-source privacy engineering platform. From 2.75.0 to before 2.83.2, Fides deployments that enable both subject identity verification and duplicate privacy request detection are affected by a vulnerability in which an administrator can approve a privacy request whose identity was never verified. For erasure policies, this can result in unauthorized deletion of a data subject's records across every integration configured in the affected deployment. This vulnerability is fixed in 2.83.2.
