CVE-2026-107395: Indico missing access check in legacy session export API

CVE-2026-107395 · Severity: medium · CVSS 4.3 · Published 2026-10-08

Indico is a web-based event management system used for conferences and meetings. A flaw in its legacy API endpoint allows an authenticated user with access to an event to retrieve restricted session metadata (titles, descriptions, organizers) without proper authorization, potentially exposing sensitive information about sessions they should not view.

Technologies: Indico, indico (PyPI). Vendors: Indico, PyPI.

Technical details

The legacy session export API endpoint fails to perform proper authorization checks on restricted sessions. An authenticated attacker with access to an event can call the API to retrieve metadata from sessions within that event that they are not authorized to view. The vulnerability requires low-privilege authentication and network access to the Indico instance, allowing information disclosure with low confidentiality impact.
