CVE-2026-25243: Redis

High severity, CVSS 8.8. EPSS: 3.7% chance of exploitation in the next 30 days.

Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3.

Affected products

• Redis Redis: before 8.6.3 (fixed in 8.6.3)
