CVE-2026-73412

Shescape is a simple shell escape library for JavaScript. Prior to 2.1.14 and 3.0.1, this impacts users of Shescape on Unix systems that explicitly configure shell to Zsh, or true when the default shell is Zsh, using the escape and escapeAll. The Zsh options EXTENDED_GLOB and MAGIC_EQUAL_SUBST exacerbate the problem. In certain case, an attacker can leverage home directory expansion and extended glob syntax to obtain lists of files and directories on the system. Depending on what the command does, this may be used to leak more information. This issue is fixed in versions 2.1.14 and 3.0.1.

Summary		(es) Shescape es una simple biblioteca de escape de shell para JavaScript. Antes de 2.1.14 y 3.0.1, esto afecta a los usuarios de Shescape en sistemas Unix que configuran explícitamente el shell a Zsh, o verdadero cuyo el shell predeterminado es Zsh, usyo escape y escapeAll. Las opciones de Zsh EXTENDED_GLOB y MAGIC_EQUAL_SUBST exacerban el problema. En cierto caso, un atacante puede aprovechar la expansión del directorio de inicio y la sintaxis de glob extendido para obtener listas de archivos y directorios en el sistema. Dependiendo de lo que haga el comyo, esto puede usarse para filtrar más información. Este problema está solucionado en las versiones 2.1.14 y 3.0.1.
