Hi,
The following vulnerabilities were published for emacs.
CVE-2022-48339[0]:
| An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has
| a command injection vulnerability. In the hfy-istext-command function,
| the parameter file and parameter srcdir come from external input, and
| parameters are not escaped. If a file name or directory name contains
| shell metacharacters, code may be executed.

CVE-2022-48338[1]:
| An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el,
| the ruby-find-library-file function has a local command injection
| vulnerability. The ruby-find-library-file function is an interactive
| function, and bound to C-c C-f. Inside the function, the external
| command gem is called through shell-command-to-string, but the
| feature-name parameters are not escaped. Thus, malicious Ruby source
| files may cause commands to be executed.

CVE-2022-48337[2]:
| GNU Emacs through 28.2 allows attackers to execute commands via shell
| metacharacters in the name of a source-code file, because lib-
| src/etags.c uses the system C library function in its implementation
| of the etags program. For example, a victim may use the "etags -u *"
| command (suggested in the etags documentation) in a situation where
| the current working directory has contents that depend on untrusted
| input.
