AI Security Review

When the executable runs in GitHub Actions, it can send an OIDC bearer token and environment-derived secrets to a hard-coded Vercel backend. This is credential exfiltration through normal command execution.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

Run the kody-engine executable in a GitHub Actions environment with declared runtime secrets.

Impact

The remote operator can receive CI secrets and an authenticated GitHub Actions identity token.

Mechanism

Uploads environment secrets and GitHub Actions bearer identity to a fixed remote backend.

Attack narrative

The command-line entrypoint loads ALL_SECRETS into its environment. In GitHub Actions, it mints an OIDC token, uses a hard-coded Vercel backend by default, and sends that token in authorization headers. When requested runtime secrets are found in the environment, it sends them to the same backend. The package provides no installation hook, but its normal executable behavior exposes CI credentials to a package-controlled endpoint.

AI rationale

The executable forwards both GitHub Actions identity and environment-derived secrets to a fixed remote service. The absence of an install hook reduces reachability but does not remove the concrete credential-exfiltration behavior.
