CVE-2025-22705 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability found in the Disqus Popular Posts plugin, specifically affecting versions up to 2.1.1. This vulnerability allows for reflected cross-site scripting (XSS) attacks, which can compromise user data and application integrity. The CVSS score of 7.1 indicates a significant risk, necessitating immediate attention from organizations using this plugin.
The vulnerability was published on February 14, 2025, and has since been classified as deferred. Although there is currently no known public exploit, the potential for attackers to leverage this vulnerability remains a concern. Organizations using the Disqus Popular Posts plugin should prioritize patching to mitigate the associated risks.
Given the nature of CSRF vulnerabilities, user interaction is required to trigger the attack, yet the low attack complexity and lack of privileges needed for exploitation highlight the urgency for organizations to address this risk promptly.
Organizations should prioritize patching immediately. Failure to address this vulnerability could result in unauthorized access and data exposure, impacting both user trust and organizational integrity.
Vulnerability Details
This vulnerability allows for reflected cross-site scripting due to improper validation of requests, leading to potential data theft or manipulation. The affected product is the Disqus Popular Posts plugin, with a specific focus on versions n/a through 2.1.1. The official CWE classification for this vulnerability is CWE-352.
The vulnerability is characterized by a CVSS score of 7.1, indicating a high severity level. The attack vector is network-based, which suggests that an attacker can exploit this vulnerability remotely. The attack complexity is low, requiring no special privileges, and user interaction is necessary for exploitation.
Technical Analysis
The root cause of CVE-2025-22705 is the insufficient validation of HTTP requests in the Disqus Popular Posts plugin. Attackers may leverage this vulnerability to forge requests that appear legitimate, thereby executing unauthorized actions. The attack vector is primarily network-based, with low complexity and no privileges required, making it accessible to a wide range of potential attackers.
User interaction is required to trigger the CSRF exploit, as victims must click on a malicious link or perform an action that sends a crafted request. The impact on confidentiality, integrity, and availability is assessed as low, but the implications of successful exploitation could lead to significant data breaches and user trust erosion.
Risk & Impact Analysis
Risk to organizations includes potential data theft and unauthorized actions taken on behalf of legitimate users. The blast radius of this vulnerability could affect all users of the Disqus Popular Posts plugin, especially those with significant user interactions. Given the high CVSS score, organizations should assess the urgency of remediation based on their environment and user base.
With an EPSS score indicating a very low probability of exploitation, the immediate threat may seem low; however, the nature of CSRF attacks means that they can be executed under specific conditions. Thus, organizations should address this vulnerability in their priority patch cycle.
