{"cve":"CVE-2023-47122","nvd":{"published":"2023-11-10T22:15:14.250","modified":"2026-06-17T06:32:11.970","status":"Modified","description":"Gitsign is software for keyless Git signing using Sigstore. In versions of gitsign starting with 0.6.0 and prior to 0.8.0, Rekor public keys were fetched via the Rekor API, instead of through the local TUF client. If the upstream Rekor server happened to be compromised, gitsign clients could potentially be tricked into trusting incorrect signatures. There is no known compromise the default public good instance (`rekor.sigstore.dev`) - anyone using this instance is unaffected. This issue was fixed in v0.8.0. No known workarounds are available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N","score":5.3},"cwes":["CWE-347"],"references":["https://docs.sigstore.dev/about/threat-model/#sigstore-threat-model","https://github.com/sigstore/gitsign/commit/cd66ccb03c86a3600955f0c15f6bfeb75f697236","https://github.com/sigstore/gitsign/pull/399","https://github.com/sigstore/gitsign/security/advisories/GHSA-xvrc-2wvh-49vc","https://docs.sigstore.dev/about/threat-model/#sigstore-threat-model"],"products":["sigstore:gitsign"],"source":"nvd","synced_at":"2026-10-19T21:42:07.670898610+00:00"},"epss":{"cve":"CVE-2023-47122","score":0.00369,"percentile":0.3087,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-xvrc-2wvh-49vc","url":"https://osv.dev/vulnerability/GHSA-xvrc-2wvh-49vc","summary":"Gitsign's Rekor public keys fetched from upstream API instead of local TUF client.","modified":"2024-08-21T14:56:43.303844Z","packages":[{"ecosystem":"Go","name":"github.com/sigstore/gitsign","purl":"pkg:golang/github.com/sigstore/gitsign","ranges":[">=0.6.0 <0.8.0"],"fixed":["0.8.0"]}]},{"id":"GO-2023-2332","url":"https://osv.dev/vulnerability/GO-2023-2332","summary":"Gitsign's Rekor public keys fetched from upstream API instead of local TUF client. in github.com/sigstore/gitsign","modified":"2026-03-03T04:51:36.055110Z","packages":[{"ecosystem":"Go","name":"github.com/sigstore/gitsign","purl":"pkg:golang/github.com/sigstore/gitsign","ranges":[">=0.6.0 <0.8.0"],"fixed":["0.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
