CVE-2025-44091 identifies a Cross Site Scripting (XSS) vulnerability in yangyouwang crud version 1.0.0, specifically within its role management function. XSS vulnerabilities occur when an application does not properly sanitize user-supplied input, allowing attackers to inject malicious scripts into web pages viewed by other users. In this case, the role management function likely accepts input that is reflected or stored and then rendered in a way that executes attacker-controlled JavaScript code in the context of the victim's browser. This can lead to session hijacking, credential theft, unauthorized actions performed on behalf of the victim, or the delivery of further malware. The vulnerability affects a specific version (1.0.0) of the yangyouwang crud application, which is a Create, Read, Update, Delete (CRUD) tool presumably used for managing data entities and user roles. No patch or fix links are currently available, and no known exploits have been reported in the wild as of the publication date (June 12, 2025). The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity. However, XSS vulnerabilities in role management modules are particularly sensitive because they can enable privilege escalation or compromise of administrative accounts if exploited. The vulnerability does not specify whether authentication or user interaction is required, but given it is in a role management function, it is likely that an authenticated user with some level of access is needed to trigger the vulnerability. The lack of detailed CWE classification and exploit indicators limits the granularity of the technical assessment, but the core issue remains a classic XSS flaw in a critical administrative component of the application.

For European organizations using yangyouwang crud v1.0.0, this XSS vulnerability in the role management function poses several risks. If exploited, attackers could execute malicious scripts in the browsers of users with access to the role management interface, potentially leading to theft of session tokens, unauthorized role changes, or lateral movement within the application. This could compromise the confidentiality and integrity of sensitive data managed by the CRUD system, especially if it is used in environments handling personal data subject to GDPR regulations. The availability impact is generally low for XSS but could escalate if attackers leverage the vulnerability to deploy further attacks or disrupt administrative functions. The threat is heightened in sectors where role management controls access to critical systems or sensitive data, such as finance, healthcare, or government agencies. Given the lack of known exploits, the immediate risk may be moderate, but the presence of an unpatched XSS in an administrative function warrants prompt attention to prevent potential targeted attacks. Additionally, exploitation could facilitate phishing or social engineering campaigns by injecting malicious content into trusted administrative interfaces.

To mitigate this vulnerability, European organizations should first identify all instances of yangyouwang crud v1.0.0 in their environments, focusing on those with role management enabled. Until an official patch is released, organizations should implement strict input validation and output encoding on the role management inputs to neutralize malicious scripts. Employing Content Security Policy (CSP) headers can reduce the risk of script execution by restricting the sources of executable scripts. Access to the role management interface should be limited to the minimum necessary users, ideally through network segmentation and multi-factor authentication to reduce the attack surface. Regular security audits and penetration testing focusing on XSS vulnerabilities in administrative modules are recommended. Monitoring web application logs for suspicious input patterns or anomalous user behavior can help detect attempted exploitation. Finally, organizations should maintain awareness of updates from the vendor or security community regarding patches or workarounds and apply them promptly once available.
