Summary

flatpak vulnerability

Details

Simon McVittie discovered that flatpak-portal service allowed sandboxed applications to execute arbitrary code on the host system (a sandbox escape). A malicious user could create a Flatpak application that set environment variables, trusted by the Flatpak "run" command, and use it to execute arbitrary code outside the sandbox.
