CVE-2026-100230
Description
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.
Statement
This issue does not affect Red Hat products. The input-leap package is only available in Fedora community repositories, and the vulnerability only affects Windows and macOS targets. On Linux, the argument parser refuses the --enable-drag-drop flag, so the vulnerable drag-and-drop file transfer code path cannot be activated. The Fedora community affect is set to NOTAFFECTED accordingly.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity
Technical Impact: Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.
Confidentiality
Technical Impact: Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
