xdg-desktop-portal: XDG Desktop Portal is a desktop integration portal
CVE-2026-55888 is fixed in xdg-desktop-portal on 1 platform by DEBIAN-CVE-2026-55888 (version 1.22.1+ds-1), released October 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
XDG Desktop Portal is a desktop integration portal. Prior to version 1.22.1, malicious sandboxed applications can use the FileChooser.SaveFiles method to gain arbitrary file access to non-existing files on the host (limited to files the user has access to). The FileChooser.SaveFiles method takes optional filenames which get appended to the selected directory by backends. The backends are supposed to check that the file does not exist yet. The filenames are not validated by the frontend and also not by common backends. This issue has been patched in version 1.22.1.
