This issue was patched in ALSA-2026:80497.

NVD Description

Note: Versions mentioned in the description apply only to the upstream flatpak package and not the flatpak package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extract_extra_data(). On system installs, the write happens as root. Two issues combine: files/extra is resolved via path operations that follow symlinks, and blob names from xa.extra-data-sources are not sanitized against .. traversal.
