FKIE_CVE-2026-44656
Vulnerability from fkie_nvd - Published: 2026-05-08 23:16 - Updated: 2026-07-24 20:10
Severity
Summary
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.

"value": "Vim es un editor de texto de c\u00f3digo abierto y de l\u00ednea de comandos. Antes de la versi\u00f3n 9.2.0435, existe una vulnerabilidad de inyecci\u00f3n de comandos del sistema operativo en la completaci\u00f3n de l\u00ednea de comandos \u0027:find\u0027 de Vim. Cuando la opci\u00f3n \u0027path\u0027 contiene comandos de shell encerrados entre comillas inversas, esos comandos se ejecutan durante la completaci\u00f3n de nombres de archivo. Debido a que la opci\u00f3n \u0027path\u0027 carece de la bandera P_SECURE, puede establecerse desde una \u0027modeline\u0027, permitiendo a un atacante que controla el contenido de un archivo ejecutar comandos de shell arbitrarios cuando el usuario abre ese archivo en Vim y activa la completaci\u00f3n \u0027:find\u0027. Este problema ha sido parcheado en la versi\u00f3n 9.2.0435."
