Proper controls are in place to require that the caller presents a valid agent certificate that is already authorized to issue at least one SPIFFE ID, and the requested SPIFFE ID belongs to the same trust domain, prior to being able to trigger this vulnerability. This issue has been fixed in SPIRE versions 0.8.5, 0.9.4, 0.10.2, 0.11.3 and 0.12.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-295"],"references":["https://github.com/spiffe/spire/security/advisories/GHSA-h746-rm5q-8mgq","https://github.com/spiffe/spire/security/advisories/GHSA-h746-rm5q-8mgq"],"products":["cncf:spire"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-27098","score":0.00558,"percentile":0.46521,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h746-rm5q-8mgq","url":"https://osv.dev/vulnerability/GHSA-h746-rm5q-8mgq","summary":"Legacy Node API Allows Impersonation in github.com/spiffe/spire/pkg/server/endpoints/node","modified":"2026-07-08T06:27:37.241138883Z","packages":[{"ecosystem":"Go","name":"github.com/spiffe/spire","purl":"pkg:golang/github.com/spiffe/spire","ranges":[">=0.8.1 <0.8.5"],"fixed":["0.8.5"]},{"ecosystem":"Go","name":"github.com/spiffe/spire","purl":"pkg:golang/github.com/spiffe/spire","ranges":[">=0.9.0 <0.9.4"],"fixed":["0.9.4"]},{"ecosystem":"Go","name":"github.com/spiffe/spire","purl":"pkg:golang/github.com/spiffe/spire","ranges":[">=0.10.0 <0.10.2"],"fixed":["0.10.2"]},{"ecosystem":"Go","name":"github.com/spiffe/spire","purl":"pkg:golang/github.com/spiffe/spire","ranges":[">=0.11.0 <0.11.3"],"fixed":["0.11.3"]},{"ecosystem":"Go","name":"github.com/spiffe/spire","purl":"pkg:golang/github.com/spiffe/spire","ranges":[">=0.12.0 <0.12.1"],"fixed":["0.12.1"]}]}],"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).
