Vulnerability Details
The official description of CVE-2026-24980 states that it allows for improper neutralization of input during web page generation, leading to reflected XSS. The vulnerability affects the NooTheme Visionary Core plugin, specifically versions from n/a through <= 1.4.9. It has been assigned the CWE classification of CWE-79, indicating its nature as an XSS vulnerability.
The CVSS score of 7.1 reflects high severity, indicating a substantial risk to users and organizations. The attack vector for this vulnerability is network-based, with a low attack complexity and no privileges required for exploitation. User interaction is necessary, which could potentially limit the attack surface but still poses a significant security risk.
Technical Analysis
The root cause of CVE-2026-24980 lies in the insufficient validation of user inputs within the Visionary Core plugin, allowing an attacker to inject malicious scripts. The attack vector is primarily network-based, as the vulnerability can be exploited over HTTP requests.
The attack complexity is low, meaning that an attacker does not require advanced skills to exploit this vulnerability. Privileges required are none, and user interaction is necessary, as the victim must click on a malicious link or perform an action that triggers the XSS payload.
The confidentiality, integrity, and availability impacts are all rated as low, indicating that while sensitive data may be exposed, the overall impact on system functionality may not be severe. However, successful exploitation could still lead to unauthorized actions being taken on behalf of users.
Risk & Impact Analysis
Organizations using the NooTheme Visionary Core plugin should assess the risk associated with CVE-2026-24980, as it can potentially lead to significant security breaches if exploited. The scope of this vulnerability is considered changed, meaning that the impact may extend beyond the immediate system to other interconnected applications or services.
The urgency for remediation is high due to the CVSS score of 7.1 and the potential for exploitation. Organizations should prioritize patching immediately and ensure that security measures are in place to prevent similar vulnerabilities in the future. Regular security assessments should be conducted to identify and mitigate risks proactively.
