description

Mage OSS/mage-ai versions through 0.9.80 can create a session when an unknown OAuth provider is supplied. An unauthenticated remote attacker may obtain a session where OAuth-based session creation is exposed.

mitigation

Update to a Mage release that includes commit 76c4f46. Until an updated release is deployed, disable or restrict OAuth-based session creation to reduce exposure.
