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 \u2014 the only check is that the field is non-empty (`pia\/oidc.py:42-52`). An approved identity provider \u2014 and every registered per-project Jenkins instance under `https:\/\/ci.eclipse.org\/\/oidc` is a separate such party (`pia\/models.py`) \u2014 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
