Title
Improper Authentication in HybridTokenAuthenticator of SAP/cloud-security-services-integration-library
Summary
The HybridTokenAuthenticator component of the SAP/cloud-security-services-integration-library accepts tokens from unintended ambient IAS/XSUAA bindings, potentially allowing unauthorized access. This vulnerability allows an attacker to gain unauthorized access to the system by using tokens that should not be accepted, leading to a breach of security.
