Prior to version 1.23.0, the Fission storagesvc component registers archive CRUD handlers (/v1/archive GET / POST / DELETE and /v1/archives list) directly on its HTTP router without performing any authentication or authorization. Any caller able to reach the storagesvc ClusterIP — including any other workload in the same Kubernetes cluster — could enumerate archive IDs, download archives belonging to other tenants, upload arbitrary archive content, and delete archives. This issue has been patched in version 1.23.0.","published":"2026-06-10T17:19:38.139Z","modified":"2026-08-12T03:51:35.972649738Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00344,"percentile":0.27066,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/fission/fission","fixedVersion":"1.23.0"}],"fix":{"url":"https://github.com/fission/fission/pull/3365","label":"fission/fission#3365"},"references":[{"type":"WEB","url":"https://github.com/fission/fission/releases/tag/v1.23.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46612.json"},{"type":"ADVISORY","url":"https://github.com/fission/fission/security/advisories/GHSA-chf8-4hv6-8pg6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46612"},{"type":"FIX","url":"https://github.com/fission/fission/pull/3365"},{"type":"FIX","url":"https://github.com/fission/fission/pull/3368"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.972649738Z"}}
