Description OSIDB Bzimport 2026-04-21 08:47:02 UTC 
nano creates ~/.local with mode 0777 instead of 0700. In permissive-umask environments (containers, CI), local attacker can race to inject malicious .desktop launcher. The subsequent mkdir for ~/.local/share correctly uses 0700.

Affected: src/history.c lines 229-234. BZ#2455314.
