What is CVE-2026-45311?

The CodeWhale product from Hmbown has a vulnerability where the run_tests tool can execute cargo test commands without user approval. This behavior, intended for automated testing, poses security risks as it allows the execution of arbitrary code, including malicious shell commands, in a compromised repository. Attackers can leverage this flaw to exfiltrate sensitive information or maintain persistence on the system, compounding the threat as the automated execution can occur at session start without user intervention. The issue has been addressed in version 0.8.23.
