• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity, no user interaction required) and the severe impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing any credentials.
• Network Access: The attack can be conducted over the network (AV:N), making it accessible from remote locations.

Exploitation Methods:

• Direct Exploitation: An attacker can send a crafted request to the 'login_admin_user' function, bypassing the authentication mechanism.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.

3. Affected Systems and Software Versions

Affected Software:

• Pedalo Connector Plugin for WordPress
• Versions: Up to and including 2.0.5

Affected Systems:

• Any WordPress installation using the Pedalo Connector plugin versions ≤ 2.0.5.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the Pedalo Connector plugin is updated to a version higher than 2.0.5.
• Temporary Disablement: If an update is not immediately available, consider temporarily disabling the plugin until a patched version is released.

Long-Term Mitigation:

• Regular Audits: Conduct regular security audits of all installed plugins and themes.
• Access Controls: Implement strict access controls and monitoring for administrative functions.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block suspicious activities targeting the 'login_admin_user' function.

5. Impact on European Cybersecurity Landscape
