CVE-2025-58237 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the LC Wizard product developed by Niaj Morshed, specifically versions up to 1.3.0. Stored XSS vulnerabilities occur when an application improperly neutralizes user-supplied input during web page generation, allowing malicious scripts to be permanently stored on the target server and later executed in the browsers of users who access the affected pages. In this case, the vulnerability allows an attacker with at least low privileges (PR:L) and requiring user interaction (UI:R) to inject malicious scripts that can compromise confidentiality, integrity, and availability of the application and its users. The CVSS v3.1 base score is 6.5 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), partial privileges required, and scope changed (S:C), indicating that the vulnerability can affect components beyond the initially vulnerable LC Wizard module. The impact includes partial loss of confidentiality, integrity, and availability, as the injected scripts can steal session tokens, manipulate displayed content, or disrupt service. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in late August 2025 and published in September 2025, indicating it is a recent discovery. The lack of patch links suggests that organizations using LC Wizard should be vigilant and consider temporary mitigations until an official fix is released.

For European organizations using LC Wizard, this vulnerability poses a moderate risk. Stored XSS can lead to session hijacking, unauthorized actions on behalf of users, data leakage, and defacement of web interfaces. Organizations in sectors with sensitive data processing, such as finance, healthcare, and government, could face reputational damage and regulatory penalties under GDPR if user data confidentiality is compromised. The scope change in the CVSS vector indicates that exploitation could affect other components or services integrated with LC Wizard, potentially amplifying the impact. Since the vulnerability requires some level of user interaction and privileges, internal users or authenticated customers could be targeted to escalate attacks. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly after public disclosure. European organizations relying on LC Wizard for web-based workflows should assess their exposure and prioritize remediation to prevent exploitation that could disrupt business operations or lead to data breaches.

1. Implement strict input validation and output encoding on all user-supplied data fields within LC Wizard, especially those that generate web page content. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the application. 3. Enforce the principle of least privilege for users interacting with LC Wizard to minimize the risk of privilege escalation via XSS. 4. Monitor web application logs for unusual input patterns or script injections that could indicate attempted exploitation. 5. Isolate LC Wizard instances in segmented network zones to limit potential lateral movement if exploited. 6. Until an official patch is released, consider disabling or restricting features that accept user-generated content or inputs that are reflected in web pages. 7. Educate users about the risks of clicking on suspicious links or interacting with untrusted content within the application. 8. Regularly update and audit third-party libraries and dependencies used by LC Wizard to reduce the attack surface.
