CVE-2026-75859CodeWhale before 0.8.64 Arbitrary File Read via instructions

Updated under an hour ago ()

Does this affect you?

It affects Hmbown CodeWhale. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

CodeWhale versions before 0.8.64 fail to validate file paths in the project config instructions field, allowing attackers to read arbitrary files on the victim's system. A malicious .codewhale/config.toml file in a cloned repository can specify paths outside the workspace that are read and injected into the AI system prompt for exfiltration.
