CVE-2026-42303 (opens in a new tab)How to fix?
Upgrade ethyca-fides to version 2.83.2rc3 or higher.
Overview
ethyca-fides is an Open-source ecosystem for data privacy as code.
Affected versions of this package are vulnerable to Improper Enforcement of Behavioral Workflow in the privacy request approval process when both subject_identity_verification_required and privacy_request_duplicate_detection.enabled are set to true. An attacker can cause unauthorized deletion of a data subject's records by submitting duplicate privacy requests using the target's email address and never completing identity verification, leading an administrator to inadvertently approve the request without proper verification. This is only exploitable if both subject_identity_verification_required and privacy_request_duplicate_detection.enabled are enabled in the deployment.
Workaround
This vulnerability can be mitigated by disabling duplicate detection by setting privacy_request_duplicate_detection.enabled to false.
