description

Apostrophe bearer-token middleware can use an unvalidated request token in a database query, allowing authentication to be bypassed. An unauthenticated attacker may access privileged data or perform administrator actions when bearer-token authentication is enabled and an active, fully verified bearer token exists.

mitigation

Upgrade the npm package apostrophe to version 4.34.1 or later. Restrict public access to affected API endpoints until the upgrade is complete.

fixed in 4.34.1
