CVE-2026-55682 Details
Description
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the auto-prepended web/html/seguranca/sessionStart.php reflects an attacker-supplied PHPSESSID cookie in a Set-Cookie response and uses DB_HOST as the cookie domain. If a victim authenticates while using the attacker-selected identifier, the attacker can reuse that identifier to hijack the authenticated session. The response also discloses the internal database host name through the cookie Domain attribute, and the vulnerable session handler affects all PHP pages. This issue is fixed in version 3.8.6.
A session fixation vulnerability has been identified in WeGIA versions prior to 3.8.6. The issue arises in the 'web/html/seguranca/sessionStart.php' file, where the PHPSESSID cookie is set based on user input without proper validation. This allows an attacker to hijack a user's session after authentication. Additionally, the internal database host name is exposed through the cookie domain, creating a potential security risk. This vulnerability affects all PHP pages within the application.
The vulnerability has been fixed in WeGIA version 3.8.6. Users should update to this version. The fix involves removing the vulnerable cookie handling code and using PHP's built-in session management functions, ensuring that session IDs are not exposed to manipulation.
