A serious vulnerability identified as CVE-2025-23511 has been discovered in the Stargazer WP-BlackCheck plugin. This vulnerability allows for Cross-Site Request Forgery (CSRF), leading to stored Cross-Site Scripting (XSS) attacks. With a CVSS score of 7.1, this vulnerability is classified as high severity, indicating that it poses significant risks to affected systems.
The vulnerability affects versions of WP-BlackCheck from n/a up to and including 2.7.2. Organizations using these versions must ensure they take appropriate actions to mitigate the risk associated with this vulnerability. The exploitation potential is elevated due to the nature of the attack vector, which is network-based, and the low complexity involved in exploiting the vulnerability.
Risk to organizations includes potential unauthorized access and manipulation of user data, which can have serious implications for data integrity and confidentiality. Organizations should prioritize patching immediately.
As of now, there are no known public exploits or proof-of-concept code available for this vulnerability, but the threat remains significant due to its classification and the potential impact on affected systems.
Vulnerability Details
The official description states: 'Cross-Site Request Forgery (CSRF) vulnerability in Stargazer WP-BlackCheck wp-blackcheck allows Stored XSS. This issue affects WP-BlackCheck: from n/a through <= 2.7.2.' This vulnerability is classified under CWE-352, which pertains to Cross-Site Request Forgery.
The CVSS 3.1 score of 7.1 signifies a high severity level, indicating that the vulnerability can be exploited with low complexity and requires user interaction. The attack vector is network-based, meaning that remote attackers can initiate the attack without physical access to the system.
The vulnerability's potential impacts include low confidentiality, integrity, and availability, making it a concerning issue for organizations relying on the affected plugin.
Technical Analysis
The root cause of this vulnerability lies in the inadequate protection against CSRF, allowing attackers to manipulate requests made by authenticated users. The attack vector is network-based, and the attack complexity is low, meaning that an attacker can exploit this vulnerability without requiring significant skill or resources.
Exploitation requires user interaction, as the victim must be tricked into performing an action without their consent. If successful, this can lead to unauthorized actions being taken on behalf of the user, compromising the integrity of their data.
The impacts on confidentiality, integrity, and availability are classified as low, indicating that while the attack does not directly compromise the system's availability, it does pose risks to user data and trust.
Risk & Impact Analysis
Real-world deployment of this vulnerability can result in unauthorized access to user accounts, leading to potential data breaches and loss of sensitive information. Organizations that leverage the WP-BlackCheck plugin for their WordPress sites are particularly at risk, as the vulnerability can be exploited without the need for elevated privileges.
As this vulnerability can lead to stored XSS, attackers may also exploit it to inject malicious scripts that could compromise user sessions or redirect users to malicious sites. The blast radius for this vulnerability can be significant, especially for organizations with a large user base or those handling sensitive user data.
Given the CVSS score and the potential impact on organizations, it is critical to address this vulnerability in a timely manner. Organizations should address in priority patch cycle.
