OS Command Injection in Vim - CVE-2026-41411

Vulnerability identifier: #VU126870

CSH Severity: Medium

CVSS v4: 5.7 [CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-41411

CWE-ID: CWE-78

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary shell commands.

The vulnerability exists due to improper neutralization of special elements used in an os command in tag file processing when resolving tag filenames from a tags file. A remote attacker can place a specially crafted tags file entry containing backtick syntax and trigger tag navigation to execute arbitrary shell commands.

User interaction is required to perform tag navigation such as :tag, Ctrl-], or vim -t after opening Vim in a directory containing a malicious tags file.
