GHSA-28c8-457r-4cf6: Path Traversal in Agent Memory Module of SAP Cloud SDK for Python

The agentmemory module accepts a caller-supplied tenant parameter in createclient(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/<tenant>/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.
