CVE-2025-10590 Overview
CVE-2025-10590 is a reflected Cross-Site Scripting (XSS) vulnerability in Portabilis i-Educar versions up to 2.10. The flaw resides in the /intranet/educar_usuario_det.php endpoint, where the ref_pessoa parameter is not properly sanitized before being reflected in the HTTP response. An attacker can craft a malicious URL that executes arbitrary JavaScript in the victim's browser when visited. The issue is classified under CWE-79 and can be triggered remotely without authentication, though it requires user interaction. Public exploit details have been released through third-party research repositories.
Critical Impact
Attackers can execute arbitrary JavaScript in an authenticated user's browser session, enabling session hijacking, credential theft, or unauthorized actions within the i-Educar application.
Affected Products
- Portabilis i-Educar versions up to and including 2.10
- Deployments exposing /intranet/educar_usuario_det.php to untrusted networks
- Web-facing i-Educar instances serving educational institutions

Technical Details for CVE-2025-10590
Vulnerability Analysis
The vulnerability is a reflected XSS flaw in the i-Educar administrative interface. The educar_usuario_det.php script accepts the ref_pessoa query parameter and renders its value back into the HTML response without adequate output encoding or input validation. An attacker who convinces an authenticated user to click a crafted link can inject arbitrary HTML or JavaScript into the rendered page.
Because the payload executes within the authenticated user's browser context, the attacker inherits the victim's session privileges. In an educational management platform, this includes access to student records, grade data, and administrative functions depending on the user's role.
Root Cause
The root cause is improper neutralization of input during web page generation [CWE-79]. The application fails to apply contextual output encoding when embedding the ref_pessoa parameter into the HTML response. Standard defenses such as HTML entity encoding, framework-level auto-escaping, or a Content Security Policy (CSP) are either absent or misconfigured for this endpoint.
Attack Vector
Exploitation is network-based and requires user interaction. An attacker constructs a URL pointing to the affected endpoint with a JavaScript payload in the ref_pessoa parameter. The attacker delivers the link through phishing email, chat, or a malicious third-party site. When an authenticated i-Educar user clicks the link, the injected script executes in their browser session. Technical proof-of-concept details are documented in the GitHub XSS Research writeup and the VulDB entry #324607.
Detection Methods for CVE-2025-10590
Indicators of Compromise
- HTTP GET requests to /intranet/educar_usuario_det.php containing ref_pessoa values with HTML tags, <script>, javascript:, onerror=, or URL-encoded equivalents such as %3Cscript%3E
- Referrer headers pointing to external domains for requests targeting the educar_usuario_det.php endpoint
- Web server access logs showing unusually long or encoded ref_pessoa parameter values
Detection Strategies
- Deploy a Web Application Firewall (WAF) rule set that inspects query parameters against known XSS payload signatures
- Enable verbose logging on the i-Educar application server and correlate parameter contents against XSS pattern libraries
- Review outbound network traffic from browsers of i-Educar users for beacons to unfamiliar domains that may indicate cookie exfiltration
Monitoring Recommendations
- Alert on any request to /intranet/educar_usuario_det.php where the ref_pessoa parameter contains reserved HTML characters
- Monitor for repeated requests from a single source with varying ref_pessoa payloads, indicating exploitation attempts
- Track browser Content Security Policy violation reports if CSP reporting endpoints are configured
How to Mitigate CVE-2025-10590
Immediate Actions Required
- Restrict access to the i-Educar administrative interface to trusted networks or VPN users until a patched version is applied
- Deploy WAF rules that block requests containing script tags or JavaScript event handlers in the ref_pessoa parameter
- Educate staff and administrators to avoid clicking i-Educar links received from untrusted sources
Patch Information
As of the last NVD update on 2026-06-17, no vendor advisory URL is listed for CVE-2025-10590. Administrators should monitor the Portabilis i-Educar project for security updates beyond version 2.10 and apply them promptly once available. Consult the VulDB advisory for updated vendor guidance.
Workarounds
- Apply a reverse proxy filter that HTML-encodes or strips reserved characters from the ref_pessoa query parameter before requests reach the application
- Configure a strict Content Security Policy (CSP) header disallowing inline script execution to reduce impact of reflected payloads
- Enforce the HttpOnly and Secure flags on session cookies to limit script-based session token theft
