Published May 8, 2026CWE-78EPSS 0.81%

Overview

CVE-2026-44656 is a medium-severity vulnerability. It was published on May 8, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. 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 version 9.2.0435, an OS command injection vulnerability exists in Vim's :find command-line completion. When the path option contains backtick-enclosed shell commands, those commands are executed during file name completion. Because the path option lacks the P_SECURE flag, it can be set from a modeline, allowing an attacker who controls the contents of a file to execute arbitrary shell commands when the user opens that file in Vim and triggers :find completion. This issue has been patched in version 9.2.0435.

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.
