AI-suggested
Until a fix is available, avoid enabling the --enable-drag-drop option on Windows or macOS. Monitor vendor communications for updates and apply official patches once released.
Description
Input Leap versions up to 3.0.3, when using the non-default --enable-drag-drop option on Windows or macOS, improperly handle path separators, allowing directory traversal via DDRG messages. This flaw can lead to code execution if an attacker writes a file to a startup directory. The vulnerability is identified as CWE-180 (Incorrect Behavior Order: Validate Before Canonicalize).
