CVE-2023-41053

Restricted key disclosure via missing SORT_RO key count

Published Sep 6, 2023 · Updated Feb 13, 2025

Improper access control in Redis 7.0.0 through 7.0.12 and 7.1.0 through 7.2.0 allows local users to read restricted keys. The sortROGetKeys function populates the command key-result array but fails to set result->numkeys, causing ACL evaluation to treat SORT_RO as accessing no keys. Exploitation requires an authenticated ACL user allowed to run SORT_RO but denied the target key, and the consequence is limited to data readable through that command.
