CVE-2025-27151

9.8 criticalEPSS 1.1%

Critical (9.8) in redis redis. EPSS 1.1% chance of exploitation in the next 30 days.

Redis is an open source, in-memory database that persists on disk. In versions starting from 7.0.0 to before 8.0.2, a stack-based buffer overflow exists in redis-check-aof due to the use of memcpy with strlen(filepath) when copying a user-supplied file path into a fixed-size stack buffer. This allows an attacker to overflow the stack and potentially achieve code execution. This issue has been patched in version 8.0.2.
