Null Pointer Micromanagement
Severity: moderate

Regular Expression Denial of Service

underscore.string

Overview

Versions of underscore.string prior to 3.3.5 are vulnerable to Regular Expression Denial of Service (ReDoS).

The function unescapeHTML is vulnerable to ReDoS due to an overly-broad regex. The slowdown is approximately 2s for 50,000 characters but grows exponentially with larger inputs.

Remediation

Upgrade to version 3.3.5 or higher.
