CVE-2025-30572 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Igor Yavych Simple Rating plugin, specifically affecting versions up to 1.4. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, potentially causing unauthorized actions. In this case, the CSRF flaw enables an attacker to inject malicious payloads that result in Stored Cross-Site Scripting (XSS). Stored XSS occurs when malicious scripts are permanently stored on the target server, such as in a database, and then served to users. This combination is particularly dangerous because it allows attackers to execute arbitrary JavaScript in the context of other users’ browsers without their consent. The vulnerability does not require user interaction beyond visiting a crafted page, and no authentication bypass is indicated, but the victim must be authenticated to the vulnerable system for the CSRF to succeed. The lack of available patches or official fixes increases the risk for organizations relying on this plugin. While no known exploits have been reported in the wild, the technical details suggest a significant risk if exploited. The vulnerability affects all installations of Simple Rating up to version 1.4, which is used primarily in content management systems or websites that implement rating features. The absence of a CVSS score necessitates an expert severity assessment based on the combined impact of CSRF and Stored XSS.

The combined CSRF and Stored XSS vulnerability can have severe consequences for affected organizations. Attackers can hijack user sessions, steal sensitive information such as authentication tokens or personal data, and perform unauthorized actions on behalf of users. This can lead to data breaches, defacement, or further compromise of the web application and its users. The Stored XSS aspect means that malicious scripts can persist on the server and affect multiple users over time, amplifying the impact. Organizations using the Simple Rating plugin in customer-facing or internal web applications risk reputational damage, loss of user trust, and potential regulatory penalties if sensitive data is exposed. The vulnerability can also be leveraged as a foothold for more advanced attacks within the network. Given the plugin's use in various CMS environments, the scope of affected systems can be broad, especially if the plugin is widely deployed without proper security controls.

To mitigate this vulnerability, organizations should immediately audit their use of the Simple Rating plugin and restrict its usage if possible until a patch is available. Implementing anti-CSRF tokens in all state-changing requests can prevent unauthorized requests from attackers. Web application firewalls (WAFs) can be configured to detect and block suspicious CSRF and XSS payloads targeting the plugin endpoints. Input validation and output encoding should be enforced rigorously to prevent injection of malicious scripts. Administrators should monitor logs for unusual activities indicative of exploitation attempts. User privileges should be minimized to reduce the impact of a successful attack. If feasible, disabling or removing the Simple Rating plugin until an official fix is released is recommended. Additionally, educating users about the risks of clicking on suspicious links can reduce the likelihood of successful CSRF attacks. Keeping all CMS and related plugins updated and subscribing to vendor security advisories will help ensure timely application of patches once available.
