An approved identity provider — and every registered per-project Jenkins instance under `https://ci.eclipse.org/<project>/oidc` is a separate such party (`pia/models.py`) — can therefore direct PIA to issue a GET request to an arbitrary host and port, including over plaintext `http`, from PIA's own network position. The fetch happens before any signature is verified, as a side effect of an unauthenticated `POST /v1/upload/sbom` request that is ultimately rejected with 401.","state":0,"publishedAt":"2026-10-20T10:06:37.127+00:00","modifiedAt":"2026-10-20T15:36:50.392+00:00","affected":[{"ecosystem":"Vendor product","name":"Eclipse CSI - PIA","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse CSI - PIA\",\n                    \"repo\": \"https://github.com/eclipse-csi/pia\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"0.8.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N","score":5.1,"severity":"MEDIUM"}],"references":["https://github.com/eclipse-csi/pia/security/advisories/GHSA-97mq-mw55-36px","https://gitlab.eclipse.org/security/cve-assignment/-/work_items/397"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107597","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107597","identifiers":["CVE-2026-107597"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
