CVE-2025-22326 is a high-severity vulnerability classified as Cross-site Scripting (XSS), specifically an improper neutralization of input during web page generation. This vulnerability allows for reflected XSS attacks in the 5centsCDN plugin, affecting versions up to and including 25.4.15. The risk is significant, as successful exploitation could lead to unauthorized actions or access to sensitive information within the context of an affected user's session.
This vulnerability has a CVSS score of 7.1, indicating high severity. It is important for organizations to understand the implications of this issue, as it requires user interaction for exploitation, but the attack vector is network-based and has low complexity. Given the potential for attackers to leverage this vulnerability, organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits or known exploitation in the wild. However, the existence of this vulnerability in a widely used plugin necessitates immediate action from organizations to mitigate risks.
Organizations should assess their use of the 5centsCDN plugin and take appropriate remediation steps to ensure that they are not vulnerable to this type of attack.
Vulnerability Details
The official description of CVE-2025-22326 describes it as an improper neutralization of input during web page generation, leading to reflected XSS. This vulnerability affects the 5centsCDN plugin versions from n/a through 25.4.15. It is classified under CWE-79, which denotes improper neutralization of input during web page generation. The CVSS score of 7.1 highlights the potential risks associated with this vulnerability, making it imperative for affected organizations to implement immediate mitigations.
Technical Analysis
The root cause of this vulnerability stems from improper input handling when generating web pages. This flaw allows attackers to inject malicious scripts into web pages viewed by other users. The attack vector is network-based; thus, it can be exploited remotely by any user who can interact with the affected web application. The complexity of the attack is low, requiring no special privileges, but it does necessitate user interaction to launch the attack.
The attack does not require any elevated privileges, which means that any user can potentially exploit the vulnerability. Confidentiality, integrity, and availability impacts are rated as low, but the overall risk to users and organizations remains critical due to the nature of XSS attacks.
Risk & Impact Analysis
Risk to organizations includes the potential for attackers to exploit this vulnerability to execute arbitrary scripts in the browser of an affected user. This could lead to unauthorized actions such as session hijacking, data theft, or redirection to malicious sites. The blast radius for this vulnerability can be significant due to the widespread use of the 5centsCDN plugin within various web applications.
Given the high CVSS score of 7.1, organizations are advised to prioritize remediation efforts as part of their security program. The lack of known exploitation does not diminish the urgency of addressing this vulnerability, as it reflects the potential for future attacks.
