Overview

CVE-2026-55895 is a high-severity vulnerability. It was published on June 25, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

Vim is an open source, command line text editor. Prior to 9.2.0663, a Vimscript code injection vulnerability exists in s:NetrwLocalRmFile() in the netrw plugin (runtime/pack/dist/opt/netrw/autoload/netrw.vim) when deleting a local file from the browser. A filename derived from the buffer's directory listing is interpolated into an Ex command line passed to :execute with only the backslash character escaped, allowing a crafted filename containing a bar (|) to terminate the intended command and execute arbitrary Vimscript, including shell commands via :call system() and :!. This vulnerability is fixed in 9.2.0663.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
