CVE-2026-32094 (GCVE-0-2026-32094)

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