CVE-2026-42303 Details
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.
A vulnerability exists in Fides versions 2.75.0 prior to 2.83.2, allowing administrators to approve duplicate privacy requests without verifying the subject's identity. This issue affects deployments that enable both identity verification and duplicate request detection. The vulnerability can lead to unauthorized deletion of a data subject's records across all integrated systems in the affected deployment. Additionally, a related denial-of-service issue, which prevented legitimate data subjects from completing privacy requests, is also addressed in the patch for this vulnerability.
Users are advised to upgrade to Fides version 2.83.2 or later. For deployments that cannot immediately upgrade, duplicate detection can be disabled in the Admin UI under Settings → Privacy Requests → Duplicate Detection.
