{"id":"CVE-2026-114439","kind":"vulnerability","aliases":["CVE-2026-114439"],"related":[],"title":"PHP travel agency system: admin session handler lets attackers skip login","description":"A vulnerability was determined in oretnom23 php-travel-agency-system. Affected by this issue is some unknown functionality of the file admin/session.php of the component Session Handler. Executing a manipulation of the argument user_id can lead to missing authentication. It is possible to launch the attack remotely. The exploit has been publicly disclosed and may be utilized. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.","summary":"The php-travel-agency-system by oretnom23 has a flaw in admin/session.php where manipulating the user_id argument bypasses authentication.
