{"id":"CVE-2022-35929","aliases":["BIT-cosign-2022-35929","GHSA-vjxv-45g9-9296","GO-2022-0758"],"url":"https://o3.security/vulnerability/CVE-2022-35929","summary":"False positive signature verification in cosign","details":"cosign is a container signing and verification utility. In versions prior to 1.10.1 cosign can report a false positive if any attestation exists. `cosign verify-attestation` used with the `--type` flag will report a false positive verification when there is at least one attestation with a valid signature and there are NO attestations of the type being verified (--type defaults to \"custom\"). This can happen when signing with a standard keypair and with \"keyless\" signing with Fulcio. This vulnerability can be reproduced with the `distroless.dev/static@sha256:dd7614b5a12bc4d617b223c588b4e0c833402b8f4991fb5702ea83afad1986e2` image. This image has a `vuln` attestation but not an `spdx` attestation. However, if you run `cosign verify-attestation --type=spdx` on this image, it incorrectly succeeds. This issue has been addressed in version 1.10.1 of cosign. Users are advised to upgrade. There are no known workarounds for this issue.","published":"2022-08-04T18:45:14Z","modified":"2026-08-12T03:51:16.772984461Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.0065,"percentile":0.48206,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":2,"affectedPackages":[{"ecosystem":"Go","name":"github.com/sigstore/cosign","fixedVersion":"1.10.1"}],"fix":{"url":"https://github.com/sigstore/cosign/commit/c5fda01a8ff33ca981f45a9f13e7fb6bd2080b94","label":"sigstore/cosign@c5fda01"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/35xxx/CVE-2022-35929.json"},{"type":"ADVISORY","url":"https://github.com/sigstore/cosign/security/advisories/GHSA-vjxv-45g9-9296"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-35929"},{"type":"FIX","url":"https://github.com/sigstore/cosign/commit/c5fda01a8ff33ca981f45a9f13e7fb6bd2080b94"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:16.772984461Z"}}
