What is CVE-2026-25154?

The LocalSend app, a free and open-source tool for sharing files and messages over local networks, is affected by a security vulnerability. In versions up to and including 1.17.0, the application initiates a local HTTP server when users start a 'Share via Link' session. This setup may potentially expose shared files to unauthorized access due to flaws in the client-side logic defined in the main.js file. Users are urged to review the security advisory and implement the necessary patches to mitigate the risk.
