[ANN] Emergency bugfix release: Org mode 9.6.23 I just released Org mode 9.6.23 that fixes several critical vulnerabilities. The release is coordinated with emergency Emacs 29.3 release (https://lists.gnu.org/archive/html/info-gnu/2024-03/msg00005.html). Please upgrade your Org mode *and* Emacs ASAP. The vulnerabilities involve arbitrary Elisp and LaTeX evaluation when previewing attachments in Emacs or when opening third-party Org files. The arbitrary Elisp evaluation is fixed by this release. The fix for LaTeX evaluation requires Emacs 29.3 and will not work for the earlier Emacs versions. If upgrading Emacs is not viable, as a workaround, you can set `org-preview-latex-default-process' to 'verbatim - this will disable LaTeX previews and avoid the vulnerability. https://list.orgmode.org/87o7b3eczr.fsf@bzg.fr/T/#t #orgmode #announcement
