Eval Injection in Vim - CVE-2026-47167

Vulnerability identifier: #VU131626

CSH Severity: Medium

CVSS v4: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-47167

CWE-ID: CWE-95

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper neutralization of directives in dynamically evaluated code in s:stepmatch() in the cucumber filetype plugin when processing crafted step-definition regex patterns from repository .rb files during step-jump handling. A remote attacker can place a specially crafted step-definition pattern in an attacker-controlled repository to execute arbitrary code.

Exploitation requires a Vim build with +ruby support and user interaction to invoke a step-jump mapping on a matching feature line.
