{"id":"CVE-2026-46614","summary":"Fission router exposes /fission-function/\u003cns\u003e/\u003cname\u003e on its public listener, allowing invocation of any function without an HTTPTrigger","details":"Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, the Fission router registers an internal-style route — /fission-function/\u003cname\u003e and /fission-function/\u003cns\u003e/\u003cname\u003e — for every Function object, independent of whether any HTTPTrigger exists for that function. The route was mounted on the same listener as user-defined HTTPTriggers (svc/router, port 8888), so any caller who could reach the router could invoke any function by guessing its metadata.name (and namespace), bypassing the host / path / method / method-allow-list restrictions encoded in HTTPTrigger objects. This issue has been patched in version 1.23.0.","aliases":["GHSA-3g33-6vg6-27m8","GO-2026-5082"],"modified":"2026-08-12T03:51:33.491240522Z","published":"2026-06-10T17:19:21.691Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46614.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-284","CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/fission/fission/releases/tag/v1.23.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46614.json"},{"type":"ADVISORY","url":"https://github.com/fission/fission/security/advisories/GHSA-3g33-6vg6-27m8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46614"},{"type":"FIX","url":"https://github.com/fission/fission/pull/3365"},{"type":"FIX","url":"https://github.com/fission/fission/pull/3369"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/fission/fission","events":[{"introduced":"0"},{"fixed":"710d8431bbbcdb82d7a1ac2b93c068baa829959b"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.23.0"}]}}],"versions":["v1.22.0","v1.22.0-rc2","v1.22.0-rc1","v1.21.0","v1.21.0-rc2","v1.21.0-rc1","v1.20.5","v1.20.4","v1.20.3","v1.20.2","v1.20.1","v1.20.0","v1.20.0-rc2","v1.20.0-rc1","v1.19.0","v1.19.0-rc2","v1.19.0-rc1","v1.18.0","v1.18.0-rc2","v1.18.0-rc1","v1.17.0","v1.17.0-rc2","v1.16.0","v1.17.0-rc1","v1.16.0-rc2","v1.16.0-rc1","v1.15.1","v1.15.0","v1.15.0-rc2","v1.15.0-rc1","v1.14.1","1.14.1","v1.14.0","1.14.0","v1.13.1","1.13.1","v1.13.0","1.13.0","v1.8.0","1.8.0","v1.7.1","1.7.1","v1.7.0","1.7.0","v1.7.0-rc.2","1.7.0-rc.2","v1.7.0-rc.1","1.7.0-rc.1","v1.6.0","1.6.0","1.3.0","1.0-rc1","0.10.0","0.7.2","0.6.1","latest","0.6.0","0.4.1","0.4.0","0.4.0rc","0.3.0","0.3.0-rc","v0.2.1","v0.2.0-20170901","nightly20170705","nightly20170621","alpha20170124","kubecon"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46614.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
