CVE-2025-54792
📛 CVE Title
LocalSend is Vulnerable to Man-in-the-Middle Attacks, Leading to File Interception
Description
LocalSend is an open-source app to securely share files and messages with nearby devices over local networks without needing an internet connection. In versions 1.16.1 and below, a critical Man-in-the-Middle (MitM) vulnerability in the software's discovery protocol allows an unauthenticated attacker on the same local network to impersonate legitimate devices, silently intercepting, reading, and modifying any file transfer. This can be used to steal sensitive data or inject malware, like ransomware, into files shared between trusted users. The attack is hardly detectable and easy to implement, posing a severe and immediate security risk. This issue was fixed in version 1.17.0.

Vulnerability mitigation is typically considered a temporary or interim solution. While mitigation measures can reduce the immediate risk associated with vulnerabilities, they may not provide a permanent fix . Organizations should aim to prioritize and plan for complete vulnerability remediation whenever feasible and allocate resources accordingly.
