CVE-2026-66775Network attack vector

Session identity binding via unprotected authentication flow

Published Aug 11, 2026 · Updated Aug 11, 2026

Cross-site request forgery in SAP Business AI Platform Approuter before 23.0.0 allows remote attackers to bind a victim session. The authentication flow does not enforce CSRF protection by default, so a crafted link can associate the victim's browser session with an attacker-controlled identity. Exploitation requires the victim to follow the link and changes session identity without reported data disclosure or service interruption.
