• Impact: The vulnerability can result in complete loss of confidentiality, integrity, and availability of the affected system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit the hardcoded passwords to gain unauthorized access to user accounts.
• Social Engineering: Attackers may use social engineering techniques to trick users into registering with social logins, thereby increasing the attack surface.
