Short explanation
In zizmor version 1.27.0, debug logging writes GitHub credentials in cleartext to the standard error output. This vulnerability can lead to unauthorized parties compromising sensitive credentials from log files.
Logging GitHub credentials in cleartext within CI/CD environments poses a significant security risk by potentially compromising repository access privileges and secrets.
What should be done?
- Follow vendor advisories and available updates
- Limit verbose logging in sensitive environments
- Revoke and rotate potentially exposed credentials
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
zizmor is a static analysis tool for CI/CD systems. In version 1.27.0, debug logging serializes the parsed application configuration with a derived Debug implementation for GitHubToken, causing credentials supplied through GH_TOKEN, GITHUB_TOKEN, ZIZMOR_GITHUB_TOKEN, --gh-token, --github-token, or --zizmor-github-token to be written to stderr in cleartext. A single -v or --verbose option or an applicable RUST_LOG directive enables the affected logging during normal online operation and --no-online-audits, while explicit --offline clears the token first. If another party can read a CI log, support artifact, terminal capture, or public bug report containing the output, the party can use the credential according to its scopes, repository access, and lifetime. This vulnerability is fixed in 1.28.0.
