Cross-app account access via unbound OAuth tokens
Published Mar 21, 2025 · Updated Mar 21, 2025
Authentication bypass in Parse Server before 7.5.2 and 8.0.0 through 8.0.1 allows remote attackers to reuse cross-app credentials. Affected authentication adapters accepted a provider access token and user ID without binding the token exchange to the destination app's client ID and secret. Exploitation requires an affected adapter and a user who signs in through the same provider to two apps, enabling access to that user's account in the other app.
