What is CVE-2026-73073?

A command injection vulnerability exists in Vim, an open source command line text editor, prior to version 9.2.0845. The flaw stems from the StructMembers() method in runtime/autoload/ccomplete.vim, which utilizes insufficiently escaped typeref or typename values from tags files. This security issue enables potential execution of arbitrary commands when a user triggers C omni-completion with CTRL-X CTRL-O on member accesses resolved from the tags file. Users are encouraged to upgrade to version 9.2.0845 or later to prevent this vulnerability.
