{"cve":"CVE-2026-46617","nvd":{"published":"2026-06-10T18:17:05.720","modified":"2026-06-17T10:53:48.360","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, Fission runtime pods were created with ServiceAccountName: fission-fetcher, and the fission-fetcher ServiceAccount was granted namespace-wide get on secrets and configmaps (it needs that to load function code, env vars, and config). The runtime pod's automounted token was reachable from inside the user's function container at /var/run/secrets/kubernetes.io/serviceaccount/token, so user-supplied function code inherited the same Kubernetes API privileges and could read any secret or configmap in the function's namespace — far beyond the Function.spec.secrets allowlist that the function specification suggests. This issue has been patched in version 1.23.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-250","CWE-269","CWE-538"],"references":["https://github.com/fission/fission/pull/3366","https://github.com/fission/fission/releases/tag/v1.23.0","https://github.com/fission/fission/security/advisories/GHSA-85g2-pmrx-r49q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-46617","score":0.00346,"percentile":0.28186,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-85g2-pmrx-r49q","url":"https://osv.dev/vulnerability/GHSA-85g2-pmrx-r49q","summary":"Fission runtime pods automount the fission-fetcher service-account token into the user function   container, granting function code namespace-wide secret / configmap read","modified":"2026-07-21T13:54:09Z","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-2026-5241","url":"https://osv.dev/vulnerability/GO-2026-5241","summary":"Fission runtime pods automount the fission-fetcher service-account token into the user function container, granting function code namespace-wide secret / configmap read in github.com/fission/fission","modified":"2026-06-25T19:45:21.834179378Z","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).
