Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the V8 JavaScript engine due to the string hashing mechanism predictably hashing integer-like strings directly to their numeric values. An attacker can exploit this by sending maliciously crafted payloads containing many colliding strings to endpoints that process user input (most commonly via JSON.parse()). This causes massive hash collisions within V8's internal string table, drastically degrading the performance of the Node.js process and resulting in a Denial of Service (DoS).
