CVE-2025-22617 Overview
CVE-2025-22617 is a Reflected Cross-Site Scripting (XSS) vulnerability in WeGIA, an open source web manager focused on Portuguese-language charitable institutions. The flaw resides in the editar_socio.php endpoint, which fails to validate and sanitize input passed through the socio parameter. Attackers can craft malicious URLs that inject JavaScript payloads reflected in the server response and executed in the victim's browser. Successful exploitation requires user interaction, typically through a phishing link. The maintainers addressed the issue in WeGIA version 3.2.7, and no workarounds are available.
Critical Impact
Attackers can execute arbitrary JavaScript in an authenticated user's browser session, enabling session theft, credential harvesting, and unauthorized actions within the WeGIA application.
Affected Products
- WeGIA versions prior to 3.2.7
- WeGIA editar_socio.php endpoint
- Deployments exposing the socio parameter to untrusted input

Technical Details for CVE-2025-22617
Vulnerability Analysis
The vulnerability is a Reflected Cross-Site Scripting flaw classified under [CWE-79]. The editar_socio.php endpoint accepts the socio parameter from HTTP requests and embeds its value directly into the HTML response without output encoding or input filtering. When a victim visits a crafted URL, the attacker-controlled payload executes within the browser under the origin of the WeGIA application.
Because WeGIA manages sensitive records for charitable institutions, script execution in an authenticated session exposes member data, financial records, and administrative functions. The attacker's JavaScript runs with the victim's privileges, permitting session cookie theft, forced navigation, and cross-origin data exfiltration through XMLHttpRequest or fetch calls.
Root Cause
The root cause is missing input validation and output sanitization on the socio parameter within editar_socio.php. The application concatenates user-supplied data into the rendered page without applying context-appropriate encoding such as htmlspecialchars(). The upstream fix in commit 35d3747 introduces sanitization to neutralize script content before reflection.
Attack Vector
Exploitation requires an attacker to deliver a crafted link to an authenticated WeGIA user through email, chat, or a compromised web page. When the victim clicks the link, the browser issues a request to editar_socio.php containing the malicious socio value. The server reflects the payload into the response, and the browser executes the script within the WeGIA origin.
The vulnerability manifests through unsanitized reflection of the socio query parameter. See the GitHub Security Advisory GHSA-8cp5-vr69-h8xx for maintainer analysis and the GitHub Commit Update for the applied fix.
Detection Methods for CVE-2025-22617
Indicators of Compromise
- HTTP requests to editar_socio.php containing <script>, onerror=, javascript:, or URL-encoded equivalents in the socio parameter
- Unexpected outbound requests from browsers rendering WeGIA pages to attacker-controlled domains
- Web server access logs showing abnormally long or encoded query strings targeting the socio parameter
Detection Strategies
- Deploy Web Application Firewall (WAF) rules that inspect the socio query parameter for HTML and JavaScript metacharacters
- Review historical web server logs for reflected payload patterns against editar_socio.php
- Enable browser Content Security Policy (CSP) violation reporting to surface script injection attempts
Monitoring Recommendations
- Alert on requests to editar_socio.php originating from external referrers or unusual geographies
- Monitor authenticated session activity for anomalous outbound HTTP requests initiated from WeGIA pages
- Correlate WeGIA access logs with endpoint telemetry to identify browsers loading suspicious query strings
How to Mitigate CVE-2025-22617
Immediate Actions Required
- Upgrade WeGIA to version 3.2.7 or later without delay
- Invalidate active sessions and force reauthentication after upgrade
- Educate administrators to avoid clicking untrusted links pointing to the WeGIA instance
Patch Information
The maintainers resolved the issue in WeGIA 3.2.7 through commit 35d374736cec39082ed297bb3cd55fa6286050ad, which adds sanitization to the socio parameter handling in editar_socio.php. Administrators should pull the release from the LabRedesCefetRJ/WeGIA repository and redeploy.
Workarounds
- No vendor-supplied workarounds exist; upgrading to 3.2.7 is the only supported remediation
- Temporary defense-in-depth: place WeGIA behind a WAF configured to block reflected XSS patterns on the socio parameter
- Enforce a strict Content Security Policy that disallows inline scripts to reduce the impact of reflected payloads
# Configuration example: WAF rule pattern to block reflected XSS on the socio parameter
# Example ModSecurity rule (adapt to your WAF syntax)
SecRule ARGS:socio "@rx (?i)(<script|onerror=|javascript:|onload=)" \
"id:1002217,phase:2,deny,status:403,msg:'CVE-2025-22617 WeGIA socio XSS attempt'"
