{"id":"CVE-2022-35930","aliases":["GHSA-739f-hw6h-7wq8","GO-2022-0759"],"url":"https://o3.security/vulnerability/CVE-2022-35930","summary":"Ability to bypass attestation verification in sigstore PolicyController","details":"PolicyController is a utility used to enforce supply chain policy in Kubernetes clusters. In versions prior to 0.2.1 PolicyController will report a false positive, resulting in an admission when it should not be admitted 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\"). An example image that can be used to test this is `ghcr.io/distroless/static@sha256:dd7614b5a12bc4d617b223c588b4e0c833402b8f4991fb5702ea83afad1986e2`. Users should upgrade to version 0.2.1 to resolve this issue. There are no workarounds for users unable to upgrade.","published":"2022-08-04T21:15:15Z","modified":"2026-08-12T03:51:26.235548874Z","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":0.00644,"percentile":0.47926,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/sigstore/policy-controller","fixedVersion":"0.2.1"}],"fix":{"url":"https://github.com/sigstore/policy-controller/commit/e852af36fb7d42678b21d7e97503c25bd1fd05c8","label":"sigstore/policy-controller@e852af3"},"references":[{"type":"WEB","url":"https://github.com/sigstore/policy-controller/releases/tag/v0.2.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/35xxx/CVE-2022-35930.json"},{"type":"ADVISORY","url":"https://github.com/sigstore/policy-controller/security/advisories/GHSA-739f-hw6h-7wq8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-35930"},{"type":"FIX","url":"https://github.com/sigstore/policy-controller/commit/e852af36fb7d42678b21d7e97503c25bd1fd05c8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.235548874Z"}}
