Exploitability: 1.6 / Impact: 3.6

Source: MITRE (Secondary)

Description

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.

Incorrect Behavior Order: Validate Before Canonicalize

The product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step.
