Prior to versions 2.11.15 and 2.12.6, users with JetStream admin API access to restore one stream could restore to other stream names, impacting data which should have been protected against them. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, if developers have configured users to have limited JetStream restore permissions, temporarily remove those permissions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N","score":4.9},"cwes":["CWE-285"],"references":["https://advisories.nats.io/CVE/secnote-2026-12.txt","https://github.com/nats-io/nats-server/security/advisories/GHSA-9983-vrx2-fg9c"],"products":["linuxfoundation:nats-server"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33222","score":0.00318,"percentile":0.24808,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9983-vrx2-fg9c","url":"https://osv.dev/vulnerability/GHSA-9983-vrx2-fg9c","summary":"NATS JetStream has an authorization bypass through its Management API","modified":"2026-09-10T03:51:00.141834623Z","packages":[{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":["<2.11.15"],"fixed":["2.11.15"]},{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":[">=2.12.0-RC.1 <2.12.6"],"fixed":["2.12.6"]},{"ecosystem":"Go","name":"github.com/nats-io/nats-server","purl":"pkg:golang/github.com/nats-io/nats-server","ranges":["all versions"],"fixed":[]}]},{"id":"GO-2026-4832","url":"https://osv.dev/vulnerability/GO-2026-4832","summary":"NATS JetStream has an authorization bypass through its Management API in github.com/nats-io/nats-server","modified":"2026-03-27T18:26:12.282997Z","packages":[{"ecosystem":"Go","name":"github.com/nats-io/nats-server","purl":"pkg:golang/github.com/nats-io/nats-server","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":["<2.11.15",">=2.12.0-RC.1 <2.12.6"],"fixed":["2.11.15","2.12.6"]}]}],"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).
