A flaw was found in Flatpak. A Time-of-check to time-of-use (TOCTOU) race condition exists in the
org.freedesktop.Flatpak.SystemHelper component. This vulnerability occurs because a privileged chmod operation executes before the OSTree repository validation within the Deploy() function. An attacker can exploit this timing window to redirect symlinks to arbitrary files, potentially leading to unauthorized file manipulation or information disclosure.Fix
