Redis: Bug in XACKDEL may lead to stack overflow and potential RCE

Published Nov 4, 2025 · Updated Feb 26, 2026 · Assigned by GitHub_M

Vendor: Redis Product: Redis Package: redis Ecosystem: Alpine

Description

Redis is an open source, in-memory database that persists on disk. In versions 8.2.0 and above, a user can run the XACKDEL command with multiple ID's and trigger a stack buffer overflow, which may potentially lead to remote code execution. This issue is fixed in version 8.2.3. To workaround this issue without patching the redis-server executable is to prevent users from executing XACKDEL operation. This can be done using ACL to restrict XACKDEL command.
