Prior to version 1.25.0, HTTPTriggerSpec.Validate() validated Methods, FunctionReference, Host, IngressConfig, and CorsConfig, but silently skipped RelativeURL and Prefix. Those two fields were validated at the CLI level only (pkg/fission-cli/cmd/httptrigger/create.go:83). The post-CRD-modernization webhook for HTTPTrigger was retired in favor of API-server CEL — and CEL had no rules on those fields either — so an HTTPTrigger created via kubectl apply or a direct Kubernetes REST API call bypassed every URL-level check. This issue has been patched in version 1.25.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-20"],"references":["https://github.com/fission/fission/pull/3464","https://github.com/fission/fission/releases/tag/v1.25.0","https://github.com/fission/fission/security/advisories/GHSA-vchh-r53j-8mpw"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-50569","score":0.00228,"percentile":0.13554,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vchh-r53j-8mpw","url":"https://osv.dev/vulnerability/GHSA-vchh-r53j-8mpw","summary":"Fission: HTTPTrigger admission omits RelativeURL / Prefix validation; kubectl apply bypasses CLI checks","modified":"2026-08-18T15:10:29.945955856Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.25.0"],"fixed":["1.25.0"]}]},{"id":"GO-2026-6131","url":"https://osv.dev/vulnerability/GO-2026-6131","summary":"Fission: HTTPTrigger admission omits RelativeURL / Prefix validation; kubectl apply bypasses CLI checks in github.com/fission/fission","modified":"2026-08-18T15:00:21.771902168Z","packages":[{"ecosystem":"Go","name":"github.com/fission/fission","purl":"pkg:golang/github.com/fission/fission","ranges":["<1.25.0"],"fixed":["1.25.0"]}]}],"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).
