Vim: Arbitrary Ex Command Execution in C Omni-Completion

Assigner: GitHub_M
Reserved: 10.08.2026 Published: 18.08.2026 Updated: 18.08.2026

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.
