SAP Cloud SDK for Pythonのエージェントメモリで別テナントの認証情報を読まれる脆弱性

The agent_memory module accepts a caller-supplied tenant parameter in create_client(tenant=...). Prior to version 0.50.0, the tenant parameter was not validated before being used to construct filesystem paths for secret resolution. A value containing path traversal sequences (for example, attacker-corp/../victim-corp) could cause the resolved path to escape the intended directory and access another tenant's secrets under:Plain Text/etc/secrets/appfnd/hana-agent-memory//Successful exploitation could allow unauthorized access to another tenant's mounted credentials, including OAuth client IDs and client secrets. This vulnerability could enable cross-tenant access to sensitive credentials.
