CVE-2026-73073

A flaw was found in Vim, an open-source command-line text editor. An attacker could craft a malicious tags file that, when processed by Vim's C omni-completion feature, leads to insufficient escaping of input. This vulnerability allows for the execution of arbitrary Ex commands and, subsequently, operating-system commands on the user's system. Successful exploitation requires a user to open a C file from an attacker-controlled tree and invoke C omni-completion on a member access whose type is resolved from the malicious tags file.

7.3 (High)


                
                  CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

CVE-2026-73073 (GCVE-0-2026-73073)

Vulnerability from cvelistv5 – Published: 2026-08-18 15:25 – Updated: 2026-08-18 15:31

Title

Vim: Arbitrary Ex Command Execution in C Omni-Completion

Summary

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.

Severity

7.1 (High)
