CVE-2025-58614 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the Jamel.Z Tooltipy product up to version 5.5.6. Stored XSS occurs when malicious input is improperly neutralized and subsequently stored by the application, then rendered unsafely in web pages viewed by other users. This vulnerability allows an attacker with at least low privileges (PR:L) and requiring user interaction (UI:R) to inject malicious scripts that execute in the context of other users' browsers. The CVSS 3.1 base score is 6.5 (medium severity), reflecting that the vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L), but requires some privileges and user interaction. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L), and the scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability arises from improper input sanitization during web page generation, allowing malicious payloads to be stored and later executed in victims' browsers, potentially leading to session hijacking, credential theft, or unauthorized actions on behalf of users.

For European organizations, this vulnerability poses a significant risk especially to those using the Tooltipy product in their web applications or services. Stored XSS can lead to data leakage, user session compromise, and unauthorized actions, which can affect customer trust and regulatory compliance, particularly under GDPR where personal data protection is critical. The medium severity score indicates a moderate risk, but the potential for scope change and impact on confidentiality, integrity, and availability means that sensitive or high-value targets could suffer notable damage. Organizations in sectors such as finance, healthcare, and government, which often handle sensitive data and rely on web-based interfaces, could face reputational damage and legal consequences if exploited. Additionally, the requirement for user interaction means phishing or social engineering could be used to trigger the exploit, increasing the risk of targeted attacks.

European organizations should immediately audit their use of the Jamel.Z Tooltipy product and identify any instances where user input is incorporated into web pages. Until an official patch is released, organizations should implement strict input validation and output encoding on all user-supplied data to neutralize potentially malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. Additionally, review and enhance user privilege management to minimize the number of users with privileges sufficient to exploit this vulnerability. Conduct user awareness training to reduce the risk of social engineering that could trigger user interaction-based exploits. Monitor web application logs for unusual input patterns or script injection attempts. Once a patch is available, prioritize its deployment. Consider deploying Web Application Firewalls (WAFs) with rules targeting known XSS payloads as a temporary protective measure.
