gpt-researcher versions 0.14.5 through 0.14.7 have an MCP STDIO configuration issue that allows arbitrary command execution. An attacker could exploit it by tricking a user into opening a crafted HTML page, which runs commands on the victim's system. No fixed version is listed, and the source gives few details.
