SB2026091401 - Argument injection in Vim

Description

This security bulletin contains information about 1 vulnerability.

1) Argument injection (CVE-ID: N/A)

CWE-ID: CWE-88 - Argument Injection or Modification

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to execute arbitrary operating system commands.

The vulnerability exists due to improper neutralization of argument delimiters in a command in sign_jump() in src/sign.c when jumping to a sign in an undisplayed buffer with a crafted file name. A local user can invoke :sign jump or sign_jump() on a buffer name containing an Ex command separator to execute arbitrary operating system commands.

Vim must be built with the +signs feature.

Remediation

Install update from vendor's website.
