Go to dashboardFlatpak's system helper can be tricked by a local user with a crafted architecture name into creating root-owned directories and files outside its intended root directory, when an OCI remote is configured. Combined with other flaws fixed in the same release, it can lead to local root privilege escalation.

Linux systems running Flatpak before 1.18.1 with at least one OCI remote configured, most commonly Fedora systems. The sources say it is not believed exploitable when no OCI remotes are configured, which is common on non-Fedora systems, and the attacker needs a local session on the machine.

flatpak --version and compare against 1.18.1.flatpak remotes --system and look for an OCI remote; the issue is not believed exploitable without one.1.18.1 or later.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. Prior to version 1.18.1, on systems where at least one OCI remote is configured (most common on Fedora systems), a malicious local user in an active local session could use a crafted architecture name to trick the flatpak-system-helper process into creating a root-owned directory tree with contents determined by the OCI remote, plus a root-owned lock file and icons directory, outside the intended root directory. If this vulnerability is combined with other vulnerabilities also fixed in 1.18.1, the combination can lead to local root privilege escalation. This particular vulnerability is not believed to be exploitable if there are no OCI remotes configured (common on non-Fedora systems). Version 1.18.1 patches the issue.
