CVE-2026-49135Public exploit

Credential disclosure and artifact tampering via fixed paths

Published Jun 1, 2026 · Updated Jun 1, 2026

Insecure temporary files in CodexBar before 0.32.0 allow local users to read notarization credentials or tamper with release archives. Scripts/sign-and-notarize.sh writes the App Store Connect API key and upload ZIP to fixed names in shared /tmp, so pre-created symlinks redirect those writes. Local access to a release host during notarization is required; exposure is limited to the notarization key and transient archive, not the Developer ID signing certificate.
