AnalysisAIv1 – Mar 12, 2026

Shescape versions prior to 2.1.10 fail to properly escape square-bracket glob patterns in Bash, BusyBox sh, and Dash, allowing attackers to manipulate shell arguments into multiple filesystem expansions instead of literal strings. Applications using the library's escape() function are vulnerable to argument injection attacks where an attacker-controlled value like "secret[12]" could expand to match multiple files, bypassing intended pathname restrictions. No patch is currently available for affected deployments.

This vulnerability (CWE-200: Information Exposure) affects Shescape is a simple shell escape library for JavaScript.. 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.
