CVE-2026-34982
Published:April 06, 2026
Updated:April 20, 2026
Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The "complete", "guitabtooltip" and "printheader" options are missing the "P_MLE" flag, allowing a modeline to be executed. Additionally, the "mapset()" function lacks a "check_secure()" call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue.
