Summary
emacs vulnerabilities
Details

It was discovered that Emacs could trigger unsafe Lisp macro expansion, when a user invoked elisp-completion-at-point on untrusted Emacs Lisp source code. An attacker could possibly use this issue to execute arbitrary code. (CVE-2024-53920)

It was discovered that Emacs did not properly sanitize input when handling certain URI schemes. An attacker could possibly use this issue to execute arbitrary shell commands by tricking a user into opening a specially crafted URL. (CVE-2025-1244)
