CVE-2026-107597— jwks_uri from the OIDC discovery document is fetched without checking its origin or scheme

Quick assessment

Affected
Eclipse Foundation Eclipse CSI - PIA
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PIA 的令牌验证逻辑（位于 中的 函数）会从白名单中的颁发者处获取 OIDC 发现文档，随后直接使用该响应中包含的 字段发起请求，而并未将其解析为 URL、未将其与已批准颁发者的源域进行比对，也未强制要求使用 HTTPS。该字段仅被检查是否非空（参见 ）。因此，任何已批准的身份提供商（包括在 下注册的每个独立项目 Jenkins 实例，这些实例在 中均被视为独立的颁发方）均可诱导 PIA 从其自身网络位置向任意主机和端口发起 GET 请求，甚至可通过明文 HTTP 协议进行。该请求的获取发生在任何签名验证之前，是

Vulnerability Title
jwks_uri from the OIDC discovery document is fetched without checking its origin or scheme
Source: CVE Program / CVE List V5
Vulnerability Description
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.
