Vim < 9.2.0845 Command Injection (CVE-2026-73073)

high Nessus Plugin ID 339352

Language:

Synopsis

A text editor installed on the remote host is affected by a command injection vulnerability.

Description

The version of Vim installed on the remote host is prior to 9.2.0845. It is, therefore, affected by a command injection vulnerability:

 - 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. (CVE-2026-73073)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Vim version 9.2.0845 or later.
