tf2-item-format is vulnerable to a Regular Expression Denial of Service (ReDoS). The vulnerability is due a regular expression with inefficient complexity utilized in decomposeName.ts, which allows an attacker to perform Denial of Service (DoS) attacks on any service that uses tf2-item-format to parse user input.
