Description Guilherme de Almeida Suckevicz 2026-10-13 19:47:11 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

GNU Emacs before 31.2 (and TRAMP through 2.8.2) allows OS command injection via a filename because tramp-user-regexp has an incomplete list of disallowed inputs. NOTE: this issue exists because of an incomplete fix for CVE-2026-79992.
