Code Injection in Vim - CVE-2026-47162

Vulnerability identifier: #VU131625

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-2026-47162

CWE-ID: CWE-94

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 control of code generation in s:NetrwBookHistSave() in the netrw plugin when serializing browsed directory paths to the history file. A remote attacker can create a specially crafted directory name to execute arbitrary code.

User interaction is required to browse the crafted directory with netrw and later open any directory so the history file is sourced. The injected content persists in the history file until the entry is rotated out.
