CVE-2025-64225 is a cross-site scripting (XSS) vulnerability identified in the colabrio Stockie Extra product, specifically affecting versions up to and including 1.2.11. The vulnerability arises from improper neutralization of script-related HTML tags within web pages generated by the application, allowing attackers to inject arbitrary code. This basic XSS flaw enables an attacker to execute malicious scripts in the context of a victim's browser session. The attack vector is remote network access without the need for authentication, but it requires user interaction, such as clicking on a malicious link or visiting a compromised page. The vulnerability has a CVSS v3.1 base score of 6.1, indicating medium severity, with a vector string of AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This means the attack can be launched remotely with low complexity, no privileges required, but user interaction is necessary. The scope is changed, indicating that the vulnerability can affect resources beyond the initially vulnerable component. The impact primarily affects confidentiality and integrity, allowing attackers to steal sensitive information or manipulate data within the application context. There are no known exploits in the wild at the time of publication, and no official patches have been released yet. The vulnerability is particularly relevant for organizations using Stockie Extra in web-facing roles, as it can facilitate session hijacking, credential theft, or delivery of further malware through injected scripts.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of data handled by Stockie Extra, especially in web-facing environments. Attackers could exploit the XSS flaw to execute malicious scripts, potentially leading to session hijacking, unauthorized data access, or manipulation of user interactions. This can result in data breaches, loss of customer trust, and regulatory non-compliance under GDPR. Sectors such as finance, healthcare, and government, which often handle sensitive personal or financial information, are particularly at risk. The medium severity score reflects that while the vulnerability does not directly impact availability, the potential for data compromise and the scope of affected systems can have significant operational and reputational consequences. Additionally, the requirement for user interaction means phishing or social engineering campaigns could be used to facilitate exploitation, increasing the threat surface. Organizations relying on Stockie Extra for critical business functions may face disruptions if attackers leverage this vulnerability as a foothold for further attacks.

To mitigate CVE-2025-64225, organizations should implement strict input validation and output encoding to neutralize script-related HTML tags before rendering content in the browser. Employing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts. User education is vital to reduce the risk of falling victim to phishing or social engineering attempts that could trigger exploitation. Network-level protections such as Web Application Firewalls (WAFs) should be configured to detect and block malicious payloads targeting this XSS vulnerability. Monitoring web traffic and logs for unusual activity related to Stockie Extra can provide early detection of exploitation attempts. Organizations should maintain close communication with the vendor for timely release and application of patches once available. In the interim, consider restricting access to the affected application to trusted users or networks where feasible. Regular security assessments and penetration testing focusing on web application vulnerabilities will help identify and remediate similar issues proactively.
