CVE-2025-58030 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the webvitaly Page-list product up to version 5.7. The vulnerability arises from improper neutralization of user input during web page generation, allowing malicious scripts to be stored and subsequently executed in the context of users viewing the affected pages. The CVSS 3.1 score of 6.5 (medium severity) reflects that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L) but requires some privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component, impacting confidentiality, integrity, and availability to a limited extent (C:L, I:L, A:L). Stored XSS can enable attackers to steal session cookies, perform actions on behalf of users, deface websites, or deliver malware. Although no known exploits are currently reported in the wild, the vulnerability's presence in a web-facing component makes it a plausible target for attackers. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability affects all versions up to 5.7, but the exact earliest affected version is unspecified (n/a).

For European organizations using the webvitaly Page-list product, this vulnerability poses risks to web application security, potentially leading to unauthorized access to user accounts, data leakage, and reputational damage. Stored XSS can facilitate targeted attacks against employees or customers, especially if the application handles sensitive or personal data subject to GDPR regulations. Exploitation could result in compliance violations and financial penalties. Additionally, the ability to execute arbitrary scripts in users' browsers can be leveraged for phishing or spreading malware within corporate networks. The medium severity suggests moderate risk, but the impact could escalate if combined with other vulnerabilities or social engineering tactics. Organizations relying on this product for public-facing or internal portals should consider the threat significant enough to warrant immediate attention to prevent exploitation and maintain trust with users and partners.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include input validation and output encoding on all user-supplied data fields to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit and sanitize stored content to detect and remove malicious payloads. Limit user privileges to minimize the ability of low-privileged users to inject harmful content. Monitor web application logs for suspicious activity indicative of XSS attempts. Additionally, organizations should engage with the vendor for timely patch releases and apply updates as soon as they become available. Incorporating web application firewalls (WAFs) with XSS detection rules can provide an additional layer of defense. Training developers and administrators on secure coding practices and vulnerability awareness is also recommended to prevent recurrence.
