The vulnerability has been assigned a CVSS v3.1 Base Score of 5.3 (Medium) with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. This scoring indicates that the vulnerability can be exploited over the network, requires low attack complexity, needs no privileges or user interaction, and primarily impacts confidentiality with no effects on integrity or availability (NVD).

The vulnerability enables unauthorized access to protected content, allowing attackers to bypass the plugin's primary security function of restricting site access to registered users only. This compromises the confidentiality of private information that was intended to be accessible only to authenticated users (NVD).

The vulnerability can be exploited by unauthenticated attackers through the API, requiring no special privileges or user interaction. The low attack complexity suggests that exploitation is straightforward, making this a significant security concern (NVD).
