GNU Emacs could allow a remote attacker to execute arbitrary code on the system, caused by a code injection flaw in org-link-expand-abbrev in lisp/ol.el. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.

Other sources

In Emacs before 29.4 org-link-expand-abbrev in lisp/ol.el expands a %(...) link abbrev even when it specifies an unsafe function such as shell-command-to-string. This affects Org Mode before 9.7.5.
