Vulnerability in MCP Python SDK could expose OAuth credentials

By PulseAugur Editorial · [2 sources] ·

Security researchers from Cycode have identified a vulnerability in the MCP Python SDK that could allow a malicious server to intercept OAuth credentials. This flaw means a compromised server could trick the SDK into sending sensitive authentication data to an attacker. The Model Context Protocol (MCP) is a standard developed by Anthropic and maintained by the Agentic AI Foundation (AAF) for connecting AI assistants with external tools. AI

IMPACT Potential for credential theft in AI-assisted tools could impact user trust and data security.

RANK_REASON Security vulnerability discovered in a specific software SDK.
