Doc Text:
A flaw was found in GNU Emacs. A remote attacker could achieve arbitrary code execution by tricking a user into opening a specially crafted file. This vulnerability arises because an untrusted value of read-symbol-shorthands affects the intern and unintern functions, allowing for code execution without specific user settings.

Description OSIDB Bzimport 2026-09-22 21:36:21 UTC
GNU Emacs 28.1 through 31.1 allows arbitrary code execution upon opening a file, because an untrusted value of read-symbol-shorthands affects the intern and unintern functions. This affects the default configuration; no particular user settings are required to trigger it.
