Prior to version 1.24.0, Fission's Environment CRD exposes spec.runtime.podSpec and spec.builder.podSpec, which are merged into the Kubernetes pod specs for runtime and builder pods. The merge logic propagated hostNetwork, hostPID, hostIPC, container privileged, and serviceAccountName from the user-supplied podspec with no filtering, and Environment.Validate performed no security-relevant checks on these fields. This issue has been patched in version 1.24.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-269","CWE-284","CWE-693"],"references":["https://github.com/fission/fission/pull/3391","https://github.com/fission/fission/releases/tag/v1.24.0","https://github.com/fission/fission/security/advisories/GHSA-gx55-f84r-v3r7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-50564","score":0.00274,"percentile":0.19878,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gx55-f84r-v3r7","url":"https://osv.dev/vulnerability/GHSA-gx55-f84r-v3r7","summary":"Fission Environment CRD podspec passthrough enables hostPID/hostNetwork/privileged pods, node escape","modified":"2026-07-07T16:11:25.335273301Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.24.0"],"fixed":["1.24.0"]}]},{"id":"GO-2026-5855","url":"https://osv.dev/vulnerability/GO-2026-5855","summary":"Fission Environment CRD podspec passthrough enables hostPID/hostNetwork/privileged pods, node escape in github.com/fission/fission","modified":"2026-07-07T16:00:36.692869653Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.24.0"],"fixed":["1.24.0"]}]}],"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).
