CVE-2026-108913
omarchy-theme-set in Omarchy 4 before 4.0.1 allows code execution via a third-party theme because the files placed into ~/.local/state/omarchy/current/theme may include executable content from an untrusted Git repository.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
