CVE-2025-7748 is a cross-site scripting (XSS) vulnerability identified in ZCMS version 3.6.0, specifically within the 'Create Article Page' component. The vulnerability arises due to improper sanitization or validation of the 'Title' parameter, which an attacker can manipulate to inject malicious scripts. This flaw allows an attacker to craft a specially crafted request that, when processed by the vulnerable ZCMS instance, results in the execution of arbitrary JavaScript code in the context of the victim's browser. The vulnerability is remotely exploitable without requiring authentication, although it requires user interaction (e.g., a user visiting a maliciously crafted page or link). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required. The impact primarily affects the integrity and confidentiality of user sessions and data, as the injected scripts can steal cookies, perform actions on behalf of the user, or redirect users to malicious sites. The vulnerability does not affect system availability or require special conditions such as user authentication or elevated privileges. Although no public exploits are currently known in the wild, the vulnerability details have been disclosed, increasing the risk of exploitation. No official patches or mitigation links are provided yet, which suggests that organizations using ZCMS 3.6.0 should prioritize risk assessment and interim protective measures.

For European organizations using ZCMS 3.6.0, this XSS vulnerability poses a significant risk to web application security, particularly for those relying on ZCMS for content management and publishing. Exploitation could lead to session hijacking, unauthorized actions on behalf of legitimate users, and potential data leakage. This can undermine user trust, damage brand reputation, and lead to regulatory compliance issues under GDPR due to potential exposure of personal data. The medium severity score reflects moderate risk; however, the ease of remote exploitation without authentication increases the threat landscape. Organizations in sectors such as media, education, government, and e-commerce that use ZCMS to manage public-facing content are especially vulnerable. Attackers could leverage this vulnerability to conduct phishing campaigns, spread malware, or deface websites, impacting service integrity and user confidence. Additionally, compromised administrative accounts could lead to further internal breaches. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate it, as public disclosure often precedes active exploitation.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'Title' parameter in article creation requests. 2) Conduct input validation and sanitization at the application level, ensuring that any user-supplied data, especially in the 'Title' field, is properly escaped or stripped of executable code before rendering. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4) Monitor web server and application logs for unusual or suspicious requests targeting the article creation functionality. 5) Educate content creators and administrators about the risks of clicking on untrusted links and encourage the use of secure browsers with updated security features. 6) Plan and prioritize upgrading to a patched version of ZCMS once available or consider temporary disabling the vulnerable component if feasible. 7) Regularly review and update security controls and incident response plans to quickly detect and respond to potential exploitation attempts.
