CVE-2026-53710 MCP Context Forge: RestrictedPython sandbox bypass via getattr builtin in python_sandbox_server

MCP Context Forge is an AI gateway, registry, and proxy for MCP, A2A, REST, and gRPC APIs. Prior to 1.0.2, the pythonsandboxserver in mcp-servers/python/pythonsandboxserver/src/pythonsandboxserver/serverfastmcp.py exposes raw getattr through safebuiltins, omits a required getattr guard, and relie...

CVE-2026-53710

MCP Context Forge (IBM) is an AI gateway and proxy for MCP, A2A, REST, and gRPC APIs. The vulnerability affects the python_sandbox_server subproject (prior to 1.0.2 ), where the RestrictedPython sandbox can be bypassed through three compounding weaknesses: raw getattr exposed in safe_builtins, ru...

CVE-2026-74896

The Python package openssl_encrypt before 1.4.0 ships a DangerousPatternVisitor AST analyzer intended to block dangerous code in plugin scripts, but it fails to recognize dunder attribute traversal chains (__class__, __bases__, __subclasses__(), __globals__). Attackers can use these chains to rea...
