CVE-2026-41049

Local privilege escalation via shared authentication cache

Published Jun 22, 2026 · Updated Jun 22, 2026

Incorrect authorization in presire qSnapper 1.2.1 through 1.3.2 allows local users to invoke privileged D-Bus restore functions. The root-running qsnapper-dbus-service stores one m_authenticated flag after a Polkit approval and reuses it across D-Bus clients instead of binding approval to the caller. Any local user can inherit the cached approval after a privileged user authenticates, and the RestoreFiles methods then provide full local root control.
