Vulnerability Details

The vulnerability is classified under CWE-290, indicating a weakness related to authentication issues. The CVSS v3.1 vector string for this vulnerability is 'CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N', which specifies that the attack vector is network-based, with low complexity and no privileges required for exploitation.

The vulnerability was published on January 27, 2025, and its last modified date is April 29, 2026. It is crucial for organizations to monitor for updates related to this vulnerability and apply relevant patches.

Technical Analysis

The root cause of this vulnerability stems from improper authentication mechanisms within the BestWebSoft Google Captcha plugin. Attackers may leverage this vulnerability to impersonate legitimate users without needing any privileges or user interaction.

The attack vector is network-based, allowing attackers to exploit the vulnerability remotely. The attack complexity is low, making it accessible for attackers with minimal skills. The impact on confidentiality is none, but there is a low impact on integrity, which can lead to unauthorized access to user identities.

Risk & Impact Analysis

Risk to organizations includes potential unauthorized access through identity spoofing, which may lead to further exploitation of sensitive data. The vulnerability's medium severity indicates that while it is not critical, the consequences of exploitation can be significant, especially if attackers leverage it as part of a broader attack.

Organizations should assess the potential blast radius of this vulnerability, particularly if the Google Captcha plugin is integrated into critical applications. Given that the vulnerability is currently deferred, it is essential to remain vigilant and prepared for any changes in its exploitation status.

Exploitation Status

Affected Versions

This vulnerability affects the BestWebSoft Google Captcha plugin versions up to 1.78. Organizations utilizing this plugin should ensure they are running a patched version to safeguard against potential identity spoofing.

Mitigation & Remediation
