CVSS 3.1
5.8 mediumCVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:LCVE-2026-76925
Medium (5.8). EPSS 0.1% chance of exploitation in the next 30 days.
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.
