Prior to version 1.23.0, the Fission router registers an internal-style route — /fission-function/<name> and /fission-function/<ns>/<name> — 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.","published":"2026-06-10T17:19:21.691Z","modified":"2026-08-12T03:51:33.491240522Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00353,"percentile":0.2801,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/fission/fission","fixedVersion":"1.23.0"}],"fix":{"url":"https://github.com/fission/fission/pull/3365","label":"fission/fission#3365"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.491240522Z"}}
