CodexBar versions prior to 0.32.0 contain an insecure temporary file handling vulnerability in the release notarization workflow. Local attackers can exploit predictable file paths to access sensitive credentials including App Store Connect API keys or tamper with build artifacts. Attackers with host access can read API keys from fixed paths, pre-create files or symbolic links at predictable locations to redirect writes to attacker-controlled destinations, or modify notarization archives before submission. The vulnerability has been addressed in version 0.32.0.
