CVE-2026-25367 identifies a Missing Authorization vulnerability in the NooTheme CitiLights theme, versions prior to 3.7.2. This vulnerability stems from improperly configured access control mechanisms within the theme, which fail to enforce correct authorization checks on certain functionality or data access points. As a result, unauthorized users may exploit this weakness to perform actions or retrieve information that should be restricted. The vulnerability is categorized under missing authorization, a common security flaw where the system does not adequately verify user permissions before granting access. No specific details about the exact functions or data affected have been disclosed, but the general risk involves unauthorized access leading to potential data leakage or unauthorized modifications. No known exploits have been reported in the wild, but the vulnerability is publicly disclosed and thus may attract attacker interest. The affected product, CitiLights by NooTheme, is a WordPress theme commonly used for business or e-commerce websites, making it a potential target for attackers seeking to compromise web assets. The absence of a CVSS score complicates severity assessment, but based on the nature of missing authorization vulnerabilities, the risk to confidentiality and integrity is significant. The vulnerability does not appear to require authentication or user interaction, increasing its exploitability. Patch information is not yet available, so organizations must rely on interim mitigations until an official fix is released.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive business data, customer information, or administrative functions within websites using the CitiLights theme. This could result in data breaches, defacement, or unauthorized transactions, undermining trust and potentially causing regulatory compliance issues under GDPR. The impact is particularly critical for e-commerce platforms, financial services, and public sector websites that rely on this theme. Loss of confidentiality and integrity could disrupt business operations and damage reputation. Since the vulnerability does not require authentication, attackers can exploit it remotely without prior access, increasing the attack surface. The absence of known exploits currently limits immediate risk, but the public disclosure increases the likelihood of future attacks. Organizations failing to address this vulnerability may face targeted attacks aiming to leverage the missing authorization flaw for data theft or site manipulation.

European organizations should prioritize upgrading the CitiLights theme to version 3.7.2 or later once the patch is released by NooTheme. Until an official patch is available, administrators should implement strict access control policies at the web server or application level to restrict access to sensitive theme functionality. This may include IP whitelisting, disabling unused features, or applying custom code to enforce authorization checks. Regularly auditing user permissions and monitoring web server logs for suspicious activity can help detect exploitation attempts early. Organizations should also consider isolating the affected web applications within segmented network zones to limit lateral movement if compromised. Engaging with the theme vendor for timely updates and subscribing to vulnerability advisories will ensure rapid response. Finally, conducting penetration testing focused on access control weaknesses can identify residual risks.
