CVE-2022-23501Network attack vector

Authenticated cross-partition account access via unsigned storage identifier

Published Dec 14, 2022 · Updated Apr 21, 2025

Improper authentication in affected TYPO3 CMS releases allows remote authenticated users to access another frontend account. Frontend login accepts a client-controlled storage page ID as the user partition selector without binding that ID to the signed request token. Exploitation requires valid credentials and duplicate usernames in separate configured storage folders, enabling access to the account in a different partition.
