Description Avinash Hanwate 2023-03-27 12:37:40 UTC

redis-py through 4.5.3 leaves a connection open after canceling an async Redis command at an inopportune time (in the case of a non-pipeline operation), and can send response data to the client of an unrelated request. NOTE: this issue exists because of an incomplete fix for CVE-2023-28858.
