Code execution via crafted MSDT URL
Published Jun 1, 2022 · Updated Aug 6, 2026
Remote code execution in Microsoft Windows MSDT allows remote attackers to run arbitrary code through a crafted ms-msdt URL. A calling application such as Word invokes the MSDT URL protocol, which passes attacker-controlled parameters to MSDT and executes code with the caller's privileges. A user must open or preview malicious content outside Office Protected View or Application Guard; successful code runs within that user's rights.
