Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for codewhale-tui, deepseek-tui, Hmbown/CodeWhale.
  2. 2Review the reported fix. Update codewhale-tui to 0.8.64; Hmbown/CodeWhale to 0.8.64; Hmbown/CodeWhale to 0.8.41; codewhale to 0.8.64; codewhale to 0.8.64; deepseek-tui to 0.8.41; deepseek-tui to 0.8.41; codewhale-tui to 0.8.64 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

CodeWhale before 0.8.64 contains a server-side request forgery bypass vulnerability in DNS pinning logic that fails to prevent time-of-check-time-of-use attacks. Attackers can manipulate DNS responses to fail initial resolution checks and succeed on secondary requests, allowing requests to internal IP addresses and bypassing SSRF mitigations.
