Doc Text:
A flaw was found in Input Leap. When the drag-and-drop file transfer feature is enabled, a connected peer can exploit improper path validation to perform directory traversal. By sending a specially crafted file transfer message, an attacker can write arbitrary files outside the intended destination directory, potentially leading to arbitrary code execution.

Description OSIDB Bzimport 2026-09-25 15:51:35 UTC
Input Leap (aka input-leap) through 3.0.3, when the non-default --enable-drag-drop option is used on Windows or macOS, mishandles the / versus \ distinction and allows directory traversal, with resultant code execution if a file is written to a startup directory. This occurs via a DDRG message.
