Code Injection in Vim - CVE-2026-55895

Vulnerability identifier: #VU134882

CSH Severity: High

CVSS v4: 8.4 [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]

CVE-ID: CVE-2026-55895

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:NetrwLocalRmFile() in the netrw plugin when deleting a local file from the browser using a crafted filename from the directory listing. A remote attacker can place a file with a crafted name containing Ex command separators and trick the victim into deleting that entry to execute arbitrary code.

User interaction is required to delete the specific crafted file entry, and exploitation is limited to environments where filenames may contain the bar character.
