Details

Regular Expression Denial of Service in underscore.string 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. ## Recommendation Upgrade to version 3.3.5 or higher.
