Authenticated SSRF via unsigned redirect cookie deserialization
Published May 14, 2026 · Updated May 14, 2026
Deserialization in DataHub before 1.5.0.3 allows remote authenticated users to send requests to internal hosts through the OIDC callback. The datahub-frontend-react GET /callback/oidc handler reads the attacker-controlled REDIRECT_URL cookie and deserializes its Java object without HMAC or encryption. OIDC must be enabled and the attacker must hold a valid identity-provider account; confirmed impact is blind SSRF and internal port scanning, while RCE was not confirmed.
