Description OSIDB Bzimport 2026-08-25 16:52:55 UTC 
Emacs TRAMP is vulnerable to a local shell command injection when processing maliciously crafted filenames. The vulnerability arises from the fact of TRAMP concatenating login arguments without a proper sanitization and further passing the result into a local shell.
