CVE-2022-35951
CWE-190Published: September 23, 2022· Updated: Jun 17, 2026
Official Description
Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. Executing an `XAUTOCLAIM` command on a stream key in a specific state, with a specially crafted `COUNT` argument may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. This has been patched in Redis version 7.0.5. No known workarounds exist.
Risk Analysis
Redis versions 7.0.0 through 7.0.4 contain an integer overflow vulnerability that can lead to a heap overflow when processing specific XAUTOCLAIM commands. This critical flaw could potentially allow remote code execution.
No public exploit is known, and it is not in the CISA KEV. It is remotely exploitable with low attack complexity.
Upgrade Redis to version 7.0.5 or later. No workarounds are available.
Technical Analysis
CVE-2022-35951 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
