Vim modeline bypass via various options affects Vim < 9.2.0276

Published Apr 6, 2026

Details

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.
