CVE-2025-55319Public exploitNetwork attack vector

Code execution via agentic command injection

Published Sep 12, 2025 · Updated Sep 12, 2025

AI command injection in Microsoft Visual Studio Code before 1.104.0 allows remote attackers to execute code through agent mode. Microsoft has not published the vulnerable function or command-construction path; release notes identify untrusted Internet content as a prompt-injection vector for agent-issued terminal commands. Exploitation requires user interaction and an agent session that processes attacker-controlled content, after which commands run with the local user's privileges.
