Claude AI finds Vim, Emacs RCE bugs that trigger on file open

**Executive summary:** The report details RCE vulnerabilities in widely used text editors: a modeline-based arbitrary command execution bug in Vim (patched in 9.2.0272) and an unpatched Emacs vector where vc-git causes Git to read and execute attacker-controlled core.fsmonitor settings from a .git/config, allowing payload execution when a user opens a crafted file or archive; users should avoid opening untrusted files and apply available patches or mitigations.
