Shescape escape() leaves bracket glob expansion active on Bash, BusyBox, and Dash

Shescape is a simple shell escape library for JavaScript. Prior to 2.1.10, Shescape#escape() does not escape square-bracket glob syntax for Bash, BusyBox sh, and Dash. Applications that interpolate the return value directly into a shell command string can cause an attacker-controlled value like secret[12] to expand into multiple filesystem matches instead of a single literal argument, turning one argument into multiple trusted-pathname matches. This vulnerability is fixed in 2.1.10.

Shescape是Eric Cornelissen个人开发者的一个用于 JavaScript 的简单外壳转义程序包。 Shescape 2.1.10之前版本存在信息泄露漏洞，该漏洞源于未转义方括号通配符语法，可能导致攻击者控制的参数扩展为多个文件系统匹配项。
