{"schema":"threatline.record/2","record":{"id":"CVE-2026-107597","aliases":["GHSA-97mq-mw55-36px"],"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/<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.","categories":["Unclassified"],"product":"Eclipse CSI - PIA","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107597","source_modified_at":"2026-10-20T15:36:50.392Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Eclipse CSI - PIA","vendor":"Eclipse Foundation","versions":[{"status":"affected","version":"0","lessThanOrEqual":"0.8.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00359,"percentile":0.28428,"score_date":"2026-10-23"},"published_at":"2026-10-20T10:06:37.127Z","modified_at":"2026-10-20T15:36:50.392Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107597","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T15:36:50.392Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107597","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-csi/pia/security/advisories/GHSA-97mq-mw55-36px"},{"source":"CVE List","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/397"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-20T15:36:39.278556Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T15:36:50.392Z","content_hash":"707e8067e4f9c9ae634e79a13d50508f4cd1180f6f7857505580f51884c72568"}}
