SB2026060172 - Code Injection in Vim

Description

This security bulletin contains information about 1 vulnerability.

1) Code Injection (CVE-ID: N/A)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to improper control of code generation in python omni-completion in python3complete.vim when processing a crafted Python file during omni-completion. A local user can place a crafted Python file with attacker-controlled import statements and a sibling package in the working directory to execute arbitrary code.

User interaction is required to invoke omni-completion with CTRL-X CTRL-O while editing the crafted Python file, and the issue affects builds with the Python interpreter enabled and filetype plugins active.

Remediation

Install update from vendor's website.
