{"id":"CVE-2026-120340","kind":"vulnerability","aliases":["CVE-2026-120340"],"related":[],"title":"CloudClassroom-PHP-Project: global session handler lets remote attackers expire sessions","description":"A weakness has been identified in mathurvishal CloudClassroom-PHP-Project. This issue affects some unknown processing of the component Global Session Handler. Executing a manipulation can lead to session expiration. The attack may be launched remotely. A high complexity level is associated with this attack. The exploitability is assessed as difficult. The exploit has been made available to the public and could be used for attacks. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way.","summary":"A weakness in the Global Session Handler of the mathurvishal CloudClassroom-PHP-Project lets a remote attacker manipulate session handling so that user sessions expire.
