CVE-2026-23479 (GCVE-0-2026-23479)

Vulnerability from cvelistv5 – Published: 2026-05-05 16:36 – Updated: 2026-05-06 03:56

Title

redis-server use-after-free in unblock client flow may allow remote code execution

Summary

Redis is an in-memory data structure store. In redis-server from 7.2.0 until 8.6.3, the unblock client flow does not handle an error return from `processCommandAndResetClient` when re-executing a blocked command. If a blocked client is evicted during this flow, an authenticated attacker can trigger a use-after-free that may lead to remote code execution. This has been patched in version 8.6.3.

Severity ?

7.7 (High)

Title

redis-server Lua use-after-free may allow remote code execution

Summary

Redis is an in-memory data structure store. In all versions of redis-server with Lua scripting, an authenticated attacker can exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled or can be disabled, which may lead to remote code execution. A workaround is to prevent users from executing Lua scripts or avoid using replicas where replica-read-only is disabled. This is patched in version 8.6.3.

Severity ?

CVE-2026-25243 (GCVE-0-2026-25243)

Vulnerability from cvelistv5 – Published: 2026-05-05 16:44 – Updated: 2026-05-06 13:24

Title

redis-server RESTORE invalid memory access may allow remote code execution

Summary

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.

Severity ?

7.7 (High)
