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.

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.
