Short explanation
CVE-2026-108388 in Indico allows restricted metadata disclosure due to incorrect handling of users during inherited event contribution management permission checks.
A low-privileged user can induce a privileged user to request a crafted legacy contribution export, causing sensitive speaker or author emails and access control entries to be stored in an API cache retrievable with less privilege.
What should be done?
- Follow vendor advisories to review updates
- Verify the installed Indico version
- Apply guidance provided in official security notifications

Show the technical text from the sources
Indico is a feature-rich event management system. Indico 3.3.3 through 3.3.13 incorrectly uses the ambient web-session user instead of the user supplied to Contribution.can_manage when checking inherited event contribution-management permission. A low-privileged user can induce a privileged user to request a crafted legacy contribution export and cause speaker or author email addresses and contribution access-control entries to be stored in an API cache entry retrievable with less privilege. This issue was fixed in Indico 3.3.14.
