Detailsinfo

A vulnerability classified as problematic has been found in KDE Dolphin up to 25.12.2. This affects an unknown code of the component FileManager1 Protocol Handler. The manipulation with an unknown input leads to a resource transfer vulnerability. CWE is classifying the issue as CWE-669. The product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.)

The advisory is shared at invent.kde.org. This vulnerability is uniquely identified as CVE-2026-41525 since 04/20/2026. The exploitability is told to be difficult. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.

Upgrading to version 25.12.3 eliminates this vulnerability.
