Hi, The following vulnerability was published for emacs. This is no fix and this is a long-standing issue, so mostly filing a bug for transparency for now: CVE-2024-53920[0]: | 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.) https://eshelyaron.com/posts/2024-11-27-emacs-aritrary-code-execution-and-how-to-avoid-it.html https://yhetil.org/emacs/CAFXAjY5f4YfHAtZur1RAqH34UbYU56_t6t2Er0YEh1Sb7-W=hg%40mail.gmail.com/ If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
