Session hijacking via persistent authentication token reuse

Published Apr 14, 2026 · Updated Apr 14, 2026

Insecure session management in SAP BusinessObjects BI Platform ENTERPRISE 430, 2025, and 2027 allows remote attackers to hijack sessions. The platform issues persistent cookies containing valid authentication tokens and continues accepting those tokens for reuse after victim authentication. Exploitation requires obtaining a victim's token and user interaction, after which the attacker gains the victim's authenticated context and can read or modify data within that session.
