Authentication-data disclosure via unchecked cross-origin pagination
Published Aug 11, 2026 · Updated Aug 11, 2026
Open redirect in SAP pyodata before 1.11.2 allows remote authenticated users to disclose authentication data through a malicious OData service. Pagination handling trusts the server-supplied __next URL and issues a subsequent request to that destination without enforcing the original service origin. Exploitation requires an attacker-controlled or compromised OData service and exposes client authentication information while allowing untrusted response data into the application.
