AI-Generated

RooCodeInc Roo-Code versions up to 3.51.1 are vulnerable to a remote code injection due to flaws in the fetch_instructions function within the malicious_mcp_server.py file of the MCP Integration Trust Model. Given that the vendor has archived the project and ceased support, organizations still using this software should prioritize remediation to mitigate potential exploitation risks. Users of this deprecated product are particularly at risk and should consider transitioning to supported alternatives.
