Last modified

CVE-2026-32094 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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. EPSS estimates a 0.21% chance of exploitation in the next 30 days.

Description

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.
