CVE-2026-105849: Payload vulnerable to API key disclosure through ordinary document reads

### Impact Users with read access to other user documents could access their active API keys. An exposed key grants the target account’s permissions until rotated or disabled. You are affected if: - An authentication collection enables `useAPIKey`. - Users have read access to other user documents containing active API keys. ### Patches Users should upgrade payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`. ### Workarounds Disable `useAPIKey` or restrict users to reading only their own authentication document. Rotate any API key that may have been exposed.
