Redis 8.4 through 8.10.1: commands queued inside a MULTI transaction are not re-checked against the client's ACL key permissions at EXEC time (the cached key-permission result of EXEC is used instead of the queued command's), so a user whose key patterns were revoked after queuing can still read or write those keys. Fixed in 8.4.7, 8.6.7, 8.8.3 and 8.10.2.
