CVE-2021-28650
autoar-extractor.c in GNOME gnome-autoar before 0.3.1, as used by GNOME Shell, Nautilus, and other software, allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink in certain complex situations.
Does this matter?
Lower severity and a low EPSS score (0.53%). Track it; it rarely justifies an emergency change on its own.
