{"id":"CVE-2026-107597","summary":"jwks_uri from the OIDC discovery document is fetched without checking its origin or scheme","details":"PIA's token verification (`verify_token` in `pia/oidc.py`) fetches the OIDC discovery document of an allowlisted issuer and then follows the `jwks_uri` contained in that response without parsing it as a URL, comparing it against the approved issuer's origin, or requiring HTTPS — the only check is that the field is non-empty (`pia/oidc.py:42-52`). An approved identity provider — and every registered per-project Jenkins instance under `https://ci.eclipse.org/\u003cproject\u003e/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.","aliases":["GHSA-97mq-mw55-36px"],"modified":"2026-10-21T02:54:36.938317174Z","published":"2026-10-20T10:06:37.127Z","database_specific":{"cna_assigner":"eclipse","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107597.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107597.json"},{"type":"PACKAGE","url":"https://github.com/eclipse-csi/pia"},{"type":"ADVISORY","url":"https://github.com/eclipse-csi/pia/security/advisories/GHSA-97mq-mw55-36px"},{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/397"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107597"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-csi/pia","events":[{"introduced":"0"},{"last_affected":"a8f8a532d60ebb9857d0820ec993f7a666c9044f"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"0.8.0"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["v0.8.0","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.1","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107597.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
