Doc Text:
A flaw was found in Redis redis-py. This flaw allows a remote, authenticated attacker to obtain sensitive information caused by an issue with leaving a connection open after canceling an async Redis command at an inopportune time. By sending a specially crafted request, an attacker can obtain sensitive information and use this information to launch further attacks against the affected system.

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.
