A vulnerability in the URL parser of Node.js could allow an unauthenticated, remote attacker to conduct spoofing attacks on a targeted system.
The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by persuading a user to access a link that submits malicious input to the targeted system. An exploit could send another arbitrary request to the system, which the attacker could use to conduct further attacks.
The Node.js Foundation has confirmed the vulnerability and released software updates.
To exploit this vulnerability, an attacker may persuade a user to access a link that submits malicious input to the targeted system by using misleading language and instructions.
