CVE-2026-100230: CWE-180 Incorrect Behavior Order: Validate Before Canonicalize in input-leap Input Leap
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.
AI Analysis
Technical Summary
CVE-2026-100230 is a vulnerability in Input Leap (input-leap) through version 3.0.3 that arises when the --enable-drag-drop option is enabled on Windows or macOS. The software mishandles the distinction between forward slash (/) and backslash (\) directory separators, leading to directory traversal. An attacker can exploit this by sending a specially crafted DDRG message to write files to arbitrary directories, including startup directories, potentially resulting in code execution.
Potential Impact
The vulnerability allows an attacker with low privileges and no user interaction to perform directory traversal, which can lead to code execution by placing malicious files in startup directories. The CVSS score is 5.3 (medium severity), indicating a moderate impact primarily on integrity with no confidentiality or availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid enabling the --enable-drag-drop option on Windows or macOS or restrict access to the Input Leap service to trusted users only.
