{"cve":"CVE-2026-46614","nvd":{"published":"2026-06-10T18:17:05.580","modified":"2026-06-17T10:53:48.157","status":"Deferred","description":"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/<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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-284","CWE-862"],"references":["https://github.com/fission/fission/pull/3365","https://github.com/fission/fission/pull/3369","https://github.com/fission/fission/releases/tag/v1.23.0","https://github.com/fission/fission/security/advisories/GHSA-3g33-6vg6-27m8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-46614","score":0.00353,"percentile":0.28979,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-3g33-6vg6-27m8","url":"https://osv.dev/vulnerability/GHSA-3g33-6vg6-27m8","summary":"Fission router exposes /fission-function/<ns>/<name> on its public listener, allowing invocation of any function without an HTTPTrigger","modified":"2026-06-25T18:56:19.283077694Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.23.0"],"fixed":["1.23.0"]}]},{"id":"GO-2026-5082","url":"https://osv.dev/vulnerability/GO-2026-5082","summary":"Fission router exposes /fission-function/<ns>/<name> on its public listener, allowing invocation of any function without an HTTPTrigger in github.com/fission/fission","modified":"2026-06-25T18:45:16.470259906Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.23.0"],"fixed":["1.23.0"]}]}],"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).
