DeepSeek MCP Server is an MCP server for DeepSeek V4. Starting in version 1.4.2 and prior to version 1.7.0, the process-global SessionStore accepts caller-supplied session id values without binding them to any authenticated principal or transport session. An attacker can enumerate active session IDs via deepseek sessions, then reuse a victim-controlled session id in deepseek chat to retrieve and continue the victim's conversation context. Version 1.7.0 contains a patch.
