Redis Flaw Allows Remote Code Execution via Stack Buffer Overflow

EXECUTIVE SUMMARY:

Redis has a high-severity vulnerability CVE-2025-62507, CVSSv4 7.7 in the XACKDEL stream command that allows attackers to trigger a stack buffer overflow by supplying an excessively large list of stream IDs through the Redis CLI or API. Successful exploitation could enable remote code execution, posing a serious risk to systems running affected Redis versions 8.2 and later. The issue stems from improper input handling during stream command processing, potentially allowing arbitrary code execution with elevated privileges.
