In versions starting from 2.2.0 but prior to 2.10.27 and 2.11.1, the management of JetStream assets happens with messages in the $JS. subject namespace in the system account; this is partially exposed into regular accounts to allow account holders to manage their assets. Some of the JS API requests were missing access controls, allowing any user with JS management permissions in any account to perform certain administrative actions on any JS asset in any other account. At least one of the unprotected APIs allows for data destruction. None of the affected APIs allow disclosing stream contents. This vulnerability is fixed in v2.11.1 or v2.10.27.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","score":9.6},"cwes":["CWE-287","CWE-306"],"references":["https://advisories.nats.io/CVE/secnote-2025-01.txt","https://github.com/nats-io/nats-server/security/advisories/GHSA-fhg8-qxh5-7q3w","http://www.openwall.com/lists/oss-security/2025/04/08/5","https://github.com/nats-io/nats-server/security/advisories/GHSA-fhg8-qxh5-7q3w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-30215","score":0.00601,"percentile":0.48771,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-fhg8-qxh5-7q3w","url":"https://osv.dev/vulnerability/GHSA-fhg8-qxh5-7q3w","summary":"NATS Server may fail to authorize certain Jetstream admin APIs","modified":"2026-09-10T03:50:23.893736901Z","packages":[{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":[">=2.11.0-RC.1 <2.11.1"],"fixed":["2.11.1"]},{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":[">=2.2.0 <2.10.27"],"fixed":["2.10.27"]}]},{"id":"GO-2025-3600","url":"https://osv.dev/vulnerability/GO-2025-3600","summary":"Missing ACLs on JavaScript APIs allowing privilege escalation github.com/nats-io/nats-server","modified":"2026-02-04T03:25:50.100934Z","packages":[{"ecosystem":"Go","name":"github.com/nats-io/nats-server/v2","purl":"pkg:golang/github.com/nats-io/nats-server/v2","ranges":[">=2.2.0 <2.10.27",">=2.11.0 <2.11.1"],"fixed":["2.10.27","2.11.1"]}]}],"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).
