CVE-2026-97027
Flatpak: flatpak: denial of service via unsanitized keys in exported desktop entry / d-bus service files
CVSS Score
3.6
EPSS Score
0.0%
EPSS Percentile
0th
Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.
