CVE-2025-33053Known exploitationNetwork attack vector

Remote code execution via shortcut WorkingDirectory path

Published Jun 10, 2025 · Updated Feb 26, 2026

Remote code execution in Microsoft Windows Internet Shortcut handling allows remote attackers to run code through a crafted .url file. The shortcut handler accepts an attacker-controlled WorkingDirectory path, causing a trusted Windows executable to search a remote WebDAV directory and load attacker-hosted code. A user must open the crafted shortcut; successful exploitation runs code in that user's context and has been observed in targeted attacks.
