CVE-2025-58971 identifies a reflected Cross-site Scripting (XSS) vulnerability in the AmentoTech Doctreat platform, a web-based application used for healthcare service management and appointment booking. The flaw stems from improper neutralization of input during web page generation, meaning that user-supplied data is not adequately sanitized before being embedded into the HTML output. This allows an attacker to craft malicious URLs or input fields that, when accessed by a victim, execute arbitrary JavaScript code within the victim's browser context. Reflected XSS typically requires the victim to click a malicious link or visit a specially crafted page. The vulnerability affects all versions of Doctreat up to and including 1.6.7. No CVSS score has been assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and considered published. The lack of patches at the time of disclosure suggests that users should be vigilant and implement interim mitigations. The impact of such an XSS vulnerability includes theft of session cookies, redirection to malicious sites, or unauthorized actions performed with the victim's privileges, potentially compromising user accounts and sensitive healthcare data. The vulnerability is particularly concerning in healthcare contexts where patient confidentiality and data integrity are paramount. The technical details confirm the vulnerability is reflected XSS, which is generally easier to exploit than stored XSS but requires user interaction. The vulnerability was reserved in early September 2025 and published in late October 2025, indicating a recent disclosure timeline.

For European organizations, especially those in healthcare, the impact of this vulnerability can be significant. Exploitation could lead to unauthorized access to patient data, session hijacking, and manipulation of user interactions within the Doctreat platform. This undermines confidentiality and integrity of sensitive healthcare information, potentially violating GDPR and other data protection regulations. Additionally, successful attacks could damage organizational reputation and trust, leading to financial and legal consequences. Since Doctreat is used for managing appointments and healthcare services, disruption or manipulation could affect service availability indirectly by causing user confusion or unauthorized changes. The reflected nature of the XSS means that phishing or social engineering could be leveraged to trick users into clicking malicious links, increasing the attack surface. European healthcare providers and service platforms relying on Doctreat must consider these risks seriously, as patient data is highly regulated and targeted by threat actors.

1. Apply vendor patches immediately once they become available for Doctreat versions up to 1.6.7. 2. Until patches are released, implement strict input validation on all user-supplied data, ensuring that special characters are properly escaped or removed before rendering in HTML contexts. 3. Employ output encoding techniques such as HTML entity encoding to neutralize potentially malicious input. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 5. Educate users and staff about the risks of clicking unknown or suspicious links, especially those related to healthcare service portals. 6. Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 7. Consider using Web Application Firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting Doctreat. 8. Conduct regular security assessments and penetration testing focused on input validation and XSS vulnerabilities. 9. Review and harden session management to limit the impact of stolen session tokens. 10. Ensure incident response plans include procedures for handling XSS exploitation scenarios in healthcare applications.
