{"id":"CVE-2025-25204","aliases":["GHSA-fgw4-v983-mgp8","GO-2025-3467"],"url":"https://o3.security/vulnerability/CVE-2025-25204","summary":"`gh attestation verify` returns incorrect exit code during verification if no attestations are present","details":"### Summary\n\nA bug in GitHub's 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 <value>` 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's predicate type does not match the specified predicate type in the command.","published":"2025-02-14T16:38:29.038Z","modified":"2026-08-12T03:51:47.937924719Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N"},"epss":{"score":0.00406,"percentile":0.34512,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/cli/cli/v2","fixedVersion":"2.67.0"}],"fix":{"url":"https://github.com/cli/cli/pull/10421","label":"cli/cli#10421"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/25xxx/CVE-2025-25204.json"},{"type":"ADVISORY","url":"https://github.com/cli/cli/security/advisories/GHSA-fgw4-v983-mgp8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-25204"},{"type":"REPORT","url":"https://github.com/cli/cli/issues/10418"},{"type":"FIX","url":"https://github.com/cli/cli/pull/10421"},{"type":"PACKAGE","url":"https://github.com/cli/cli"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.937924719Z"}}
