——16Gibbon v23 does not generate a new session ID cookie after a user authenticates, making the application vulnerable to session fixation.10dCVE-2024-236799.8 CRI53.7%
——16Enonic XP versions less than 7.7.4 are vulnerable to a session fixation issue. An remote and unauthenticated attacker can use prior sessions due to the lack of invalidating session attributes.4dCVE-2023-300567.5 HIG49.9%
——15A session takeover vulnerability exists in FICO Origination Manager Decision Module 4.8.1 due to insufficient protection of the JSESSIONID cookie.10dCVE-2025-459499.8 CRI34.5%
——10A critical vulnerability was found in PHPGurukul User Registration & Login and User Management System V3.3 in the /loginsystem/change-password.php file of the user panel - Change Password component. Improper handling of session data allows a Session Hijacking attack, exploitable remotely and leading to account takeover.14dCVE-2026-337579.6 CRI33.3%
——10OpenBao is an open source identity-based secrets management system. Prior to version 2.5.2, OpenBao does not prompt for user confirmation when logging in via JWT/OIDC and a role with `callback_mode` set to `direct`. This allows an attacker to start an authentication request and perform "remote phishing" by having the victim visit the URL and automatically log-in to the session of the attacker. Despite being based on the authorization code flow, the `direct` mode calls back directly to the API and allows an attacker to poll for an OpenBao token until it is issued. Version 2.5.2 includes an additional confirmation screen for `direct` type logins that requires manual user interaction in order to finish the authentication. This issue can be worked around either by removing any roles with `callback_mode=direct` or enforcing confirmation for every session on the token issuer side for the Client ID used by OpenBao.3dCVE-2025-459539.1 CRI28.3%
——8A vulnerability was found in PHPGurukul Hostel Management System 2.1 in the /hostel/change-password.php file of the user panel - Change Password component. Improper handling of session data allows a Session Hijacking attack, exploitable remotely14d
