Upgrade ethyca-fides to version 2.24.0 or higher.
Overview
ethyca-fides is an Open-source ecosystem for data privacy as code.
Affected versions of this package are vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) when the subject_identity_verification_required function is enabled. An attacker can predict all future one-time code values during the lifetime of the backend python process by generating several hundred consecutive one-time codes. This allows the attacker to submit a verified data erasure request, resulting in deletion of data for the targeted user and submit a verified consent request, modifying a user's privacy preferences. This is only exploitable if subject_identity_verification_required in the [execution] section of fides.toml or the env var FIDES__EXECUTION__SUBJECT_IDENTITY_VERIFICATION_REQUIRED is set to True on the fides webserver backend.
