CVE-2026-55888XDG Desktop Portal is a desktop integration portal Executive summary The advisory concerns XDG Desktop Portal, a desktop integration component, and describes several security fixes in release 1.22.1. The issues let sandboxed applications interfere with data transfers or write to or read files outside their sandbox. The advisory does not state a severity score, and the fixes are delivered in version 1.22.1. Technical summary The advisory describes three security fixes: a predictable key in FileTransfer.RetrieveFiles that lets a malicious sandboxed application redirect drag-and-drop and copy-paste data to itself (GHSA-c5cf-79w8-pvfh), arbitrary write access to nonexistent files outside the sandbox via the files option in FileChooser.SaveFiles (GHSA-cm83-2936-gxjm), and unvalidated App IDs in the Document Portal that could cause arbitrary host files to be parsed as Glib.KeyFile objects (#2023). The fixed release is 1.22.1. Affected version ranges, CVSS score, exploitation status, workarounds, and detection guidance are not stated in the advisory. The attack requires a malicious sandboxed application. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
