Description

In elisp-mode.el in GNU Emacs through 30.0.92, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.)
A flaw was found in the Emacs text editor. Due to unsafe macro expansion, a specially-crafted Lisp source code file may trigger arbitrary code execution. A user who has configured `elisp-completion-at-point` for code completion or enabled automatic error checking such as Flymake or Flycheck on untrusted Lisp files is vulnerable to this issue.
