Starting in version 2.49.0 and prior to version 2.67.0, under certain conditions, a bug in GitHub\u0027s Artifact Attestation cli tool `gh attestation verify` causes it to return a zero exit status when no attestations are present. This behavior is incorrect: When no attestations are present, `gh attestation verify` should return a non-zero exit status code, thereby signaling verification failure. An attacker can abuse this flaw to, for example, deploy malicious artifacts in any system that uses `gh attestation verify`\u0027s exit codes to gatekeep deployments. Users are advised to update `gh` to patched version `v2.67.0` as soon as possible."

  "details": "### Summary\n\nA bug in GitHub\u0027s Artifact Attestation CLI tool, `gh attestation verify`, may return an incorrect zero exit status when no matching attestations are found for the specified `--predicate-type \u003cvalue\u003e` or the default `https://slsa.dev/provenance/v1` if not specified. This issue only arises if an artifact has an attestation with a predicate type different from the one provided in the command. As a result, users relying solely on these exit codes may mistakenly believe the attestation has been verified, despite the absence of an attestation with the specified predicate type and the tool printing a verification failure.\n\nUsers are advised to update `gh` to version `v2.67.0` as soon as possible.\n\nInitial report: https://github.com/cli/cli/issues/10418\nFix: https://github.com/cli/cli/pull/10421\n\n### Details\n\nThe gh attestation verify command fetches, loads, and attempts to verify attestations associated with a given artifact for a specified predicate type. If an attestation is found, but the predicate type does not match the one specified in the `gh attestation verify` command, the verification fails, but the program exits early.\n\nDue to a re-used uninitialized error variable, when no matching attestations are found, the relevant function returns `nil` instead of an error, causing the program to exit with a status code of `0`, which incorrectly suggests successful verification.\n\n### PoC\n\nRun `gh attestation verify` with local attestations using the `--bundle` flag and specify a predicate type with `--predicate-type` that you know will not match any of the attestations the command will attempt to verify. Confirm that the command exits with a zero status code.\n\n### Impact\n\nUsers who rely exclusively on the exit status code of `gh attestation verify` may incorrectly verify an attestation when the attestation\u0027s predicate type does not match the specified predicate type in the command.",
