CVE-2026-73073

Published: August 20, 2026Last modified: August 20, 2026

Description

Vim is an open source, command line text editor. Prior to 9.2.0845, StructMembers() in runtime/autoload/ccomplete.vim constructs and executes a vimgrep command using an insufficiently escaped typeref: or typename: value from a tags file, allowing an unterminated collection followed by a command separator to execute arbitrary Ex and operating-system commands when a user invokes C omni-completion with CTRL-X CTRL-O on a member access whose type is resolved from that tags file. This issue is fixed in version 9.2.0845.
