CVE-2026-25243
CVE-2026-25243 · redis-server RESTORE invalid memory access may allow remote code execution
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
