In versions prior to 1.12.0 a number of vulnerabilities have been found in cosign verify-blob, where Cosign would successfully verify an artifact when verification should have failed. First a cosign bundle can be crafted to successfully verify a blob even if the embedded rekorBundle does not reference the given signature. Second, when providing identity flags, the email and issuer of a certificate is not checked when verifying a Rekor bundle, and the GitHub Actions identity is never checked. Third, providing an invalid Rekor bundle without the experimental flag results in a successful verification. And fourth an invalid transparency log entry will result in immediate success for verification. Details and examples of these issues can be seen in the GHSA-8gw7-4j42-w388 advisory linked. Users are advised to upgrade to 1.12.0. There are no known workarounds for these issues.","references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2022-36056.json","reference_id":"","reference_type":"","scores":[{"value":"4.1","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2022-36056.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2022-36056","reference_id":"","reference_type":"","scores":[{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04978","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04958","published_at":"2026-06-04T12:55:00Z"},{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04955","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04919","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04957","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.04965","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2022-36056"},{"reference_url":"https://github.com/sigstore/cosign","reference_id":"","reference_type":"","scores":[{"value":"5.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/sigstore/cosign"},{"reference_url":"https://github.com/sigstore/cosign/commit/80b79ed8b4d28ccbce3d279fd273606b5cddcc25","reference_id":"","reference_type":"","scores":[{"value":"5.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2025-04-22T15:44:20Z/"}],"url":"https://github.com/sigstore/cosign/commit/80b79ed8b4d28ccbce3d279fd273606b5cddcc25"},{"reference_url":"https://github.com/sigstore/cosign/releases/tag/v1.12.0","reference_id":"","reference_type":"","scores":[{"value":"5.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/sigstore/cosign/releases/tag/v1.12.0"},{"reference_url":"https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388","reference_id":"","reference_type":"","scores":[{"value":"5.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2025-04-22T15:44:20Z/"}],"url":"https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36056","reference_id":"","reference_type":"","scores":[{"value":"5.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36056"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2128820","reference_id":"2128820","reference_type":"","scores":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2128820"},{"reference_url":"https://access.redhat.com/errata/RHSA-2022:8827","reference_id":"RHSA-2022:8827","reference_type":"","scores":[],"url":"https://access.redhat.com/errata/RHSA-2022:8827"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/484127?format=json","purl":"pkg:apk/alpine/cosign@1.12.1-r0?arch=riscv64&distroversion=v3.21&reponame=community","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/cosign@1.12.1-r0%3Farch=riscv64&distroversion=v3.21&reponame=community"}],"aliases":["CVE-2022-36056","GHSA-8gw7-4j42-w388"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-bj9d-n8sh-ybhm"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/cosign@1.12.1-r0%3Farch=riscv64&distroversion=v3.21&reponame=community"}
