CVE-2026-73519Network attack vector

Unauthenticated container command execution via default secret

Published Aug 12, 2026 · Updated Aug 12, 2026

Authentication bypass in WolfStack before 25.9.2 allows remote attackers to execute commands as root in managed containers. require_auth() accepts a published constant from src/auth/mod.rs in the X-WolfStack-Secret header as a cluster-node identity without a session, API key, or account. Exploitation requires network access to the management port and a node still using the built-in default; host compromise depends on container privileges, bind mounts, or shared namespaces.
