Doc Text:	A flaw was found in KDE Dolphin. This vulnerability allows applications operating within a Flatpak or AppArmor sandbox to bypass security restrictions. By exploiting the FileManager1 protocol, a malicious application can prompt users to open files, including scripts or executables, located outside the application's designated sandbox, potentially leading to unintended code execution.

Description OSIDB Bzimport 2026-04-28 08:01:30 UTC

KDE Dolphin before 25.12.3 allows applications in a Flatpak (or with AppArmor confinement) to open folders outside of the application sandbox without additional scrutiny. Dolphin's implementation of the FileManager1 protocol allows the path given to be any type of file, including scripts or executables. (By default, Dolphin will then prompt the user to determine if they want to launch a script or executable; however, the intended behavior is to block the attempted action, not present a consent prompt.)
