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.

**Am I affected by CVE-2026-107395?** Check whether you run Indico or indico (PyPI) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- indico (PyPI): upgrade to 3.3.13 or later

  ```sh
  pip install "indico>=3.3.13"
  ```


Restrict access to the event itself to limit who can interact with any APIs relating to that event.

## 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.
