Summary Multiple vulnerabilities were addressed in IBM Observability with Instana OnPrem build 1.0.323 Vulnerability Details CVEID:CVE-2026-48776 DESCRIPTION: LangGraph Python SDK is used to connect to running LangGraph API servers, manage assistants, threads and stream runs from Python...

PT-2026-59232

Summary langgraph-sdk constructs HTTP request paths for resource operations by interpolating caller-supplied identifier values into URL templates. Without sanitization of those values, identifiers that contain characters with special meaning in URL paths could cause the resulting request to addre...
