Prior to version 1.24.0, Fission's Container Executor path lets a tenant supply Function.spec.podspec directly; the executor merges it into the executor-built podspec and creates a Deployment whose pods run the user's container image. This issue has been patched in version 1.24.0.","published":"2026-06-10T17:27:18.502Z","modified":"2026-08-12T03:51:27.264436811Z","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/fission/fission","fixedVersion":"1.24.0"}],"fix":{"url":"https://github.com/fission/fission/pull/3391","label":"fission/fission#3391"},"references":[{"type":"WEB","url":"https://github.com/fission/fission/releases/tag/v1.24.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50563.json"},{"type":"ADVISORY","url":"https://github.com/fission/fission/security/advisories/GHSA-v455-mv2v-5g92"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50563"},{"type":"FIX","url":"https://github.com/fission/fission/pull/3391"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:27.264436811Z"}}
