Technical details
The vulnerability exists in PyCharm's Jupyter MCP tools implementation, which failed to properly authenticate requests before executing code. The lack of authentication controls on the MCP tools allowed remote attackers to send malicious requests over the network to execute arbitrary code with the privileges of the PyCharm process. No user interaction or prior authentication is required; an attacker with network access to a vulnerable PyCharm instance can directly trigger code execution. The vulnerability was resolved in PyCharm version 2026.2.1 and later.
