CVE-2025-28245 is a cross-site scripting (XSS) vulnerability identified in Alteryx Server version 2023.1.1.460. This vulnerability allows remote attackers to inject arbitrary web scripts or HTML content through the notification body feature of the server. XSS vulnerabilities occur when an application does not properly sanitize user-supplied input, enabling attackers to execute malicious scripts in the context of a victim's browser session. In this case, the injection point is the notification body, which is likely rendered in the web interface of Alteryx Server. Successful exploitation could allow attackers to perform actions such as stealing session cookies, redirecting users to malicious sites, or executing unauthorized commands within the victim's browser session. Although no known exploits are currently reported in the wild, the vulnerability's presence in a data analytics platform like Alteryx Server poses a risk, especially in environments where sensitive data is processed and accessed via web interfaces. The lack of a CVSS score indicates that the vulnerability is newly published and has not yet been fully assessed for severity or impact. The absence of patch links suggests that a fix may not yet be publicly available, increasing the urgency for organizations to implement interim mitigations.

For European organizations, the impact of this XSS vulnerability could be significant, particularly for those relying on Alteryx Server for data analytics and business intelligence. Exploitation could lead to unauthorized access to sensitive analytical data, session hijacking, and potential lateral movement within the network if attackers leverage stolen credentials or session tokens. This could compromise data confidentiality and integrity, and potentially disrupt availability if attackers inject scripts that alter server behavior or user workflows. Organizations in regulated sectors such as finance, healthcare, and government could face compliance violations and reputational damage if sensitive data is exposed. Additionally, since Alteryx Server is often integrated into broader data ecosystems, the vulnerability could serve as an entry point for more extensive attacks targeting critical infrastructure or intellectual property within European enterprises.

Given the absence of an official patch, European organizations should adopt a multi-layered mitigation approach. First, implement strict input validation and output encoding on the notification body fields if customization or internal development is possible. Employ web application firewalls (WAFs) configured to detect and block common XSS attack patterns targeting the Alteryx Server web interface. Limit user privileges to reduce the risk of malicious notification content being submitted by unauthorized users. Monitor server logs and network traffic for unusual activity related to notification submissions or web interface interactions. Educate users about the risks of clicking on unexpected links or interacting with suspicious notifications. Once a patch becomes available, prioritize its deployment in all affected environments. Additionally, consider isolating Alteryx Server instances within segmented network zones to limit potential lateral movement in case of compromise.
