CVE-2025-24876Network attack vector

Victim session theft via authorization code injection

Published Feb 11, 2025 · Updated Feb 21, 2025

Authentication bypass in SAP Approuter 2.6.1 through 16.7.1 allows remote attackers to steal a victim's session via authorization code injection. SAP identifies the authorization-code exchange as the affected locus but has not published which input validation or session-binding operation accepts the malicious payload. Exploitation requires victim interaction but no attacker privileges, and the stolen session permits data access and modification without interrupting service.
