JSON

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.
