CVE-2025-67733 (GCVE-0-2025-67733)

Vulnerability from cvelistv5 – Published: 2026-02-23 19:39 – Updated: 2026-02-25 14:57

Title

Valkey Affected by RESP Protocol Injection via Lua error_reply

Summary

Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious user can use scripting commands to inject arbitrary information into the response stream for the given client, potentially corrupting or returning tampered data to other users on the same connection. The error handling code for lua scripts does not properly handle null characters. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue.

Severity ?

8.5 (High)

CVE-2026-21863 (GCVE-0-2026-21863)

Vulnerability from cvelistv5 – Published: 2026-02-23 19:41 – Updated: 2026-02-25 14:58

Title

Malformed Valkey Cluster bus message can lead to Remote DoS

Summary

Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious actor with access to the Valkey clusterbus port can send an invalid packet that may cause an out bound read, which might result in the system crashing. The Valkey clusterbus packet processing code does not validate that a clusterbus ping extension packet is located within buffer of the clusterbus packet before attempting to read it. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue. As an additional mitigation, don't expose the cluster bus connection directly to end users, and protect the connection with its own network ACLs.

Severity ?

7.5 (High)

Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious actor with access to the Valkey clusterbus port can send an invalid packet that may cause an out bound read, which might result in the system crashing. The Valkey clusterbus packet processing code does not validate that a clusterbus ping extension packet is located within buffer of the clusterbus packet before attempting to read it. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue. As an additional mitigation, don\u0027t expose the cluster bus connection directly to end users, and protect the connection with its own network ACLs."
