CVE-2026-14336

HIGH
8.2
CVSS 3.1
Description
PIA's OIDC issuer allowlist for Jenkins tokens uses a bare string-prefix check (issuer.startswith(' https://ci.eclipse.org ') in is_issuer_known, pia/models.py:139) instead of validating the issuer as a properly host-bounded URL. An attacker can craft an issuer such as https://ci.eclipse.org@evil.host (userinfo trick) or https://ci.eclipse.org.evil.host (suffix trick) that satisfies the prefix check while pointing the OIDC discovery and JWKS fetches at a server the attacker controls. An unauthenticated caller of POST /v1/upload/sbom can use this to force PIA to make outbound HTTP(S) requests to an arbitrary attacker-chosen host, and to have oidc.verify_token accept a JWT signed with the attacker's own key.
