CVE-2025-27151: Redis

Critical severity, CVSS 9.8. EPSS: 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.

Affected products

• Redis Redis: from 7.0.0, before 7.2.9 (fixed in 7.2.9); from 7.4.0, before 7.4.4 (fixed in 7.4.4); from 8.0.0, before 8.0.2 (fixed in 8.0.2)
