MEDIUM

People: Privilege Escalation via Missing Role Ceiling in Mail Domain Invitation

Title source: cna
STIX 2.1

Description

People is an application to handle users and teams, and distribute permissions across La Suite. Prior to version 1.25.0, a user holding the Administrator role on a mail domain could send a crafted invitation request to promote any existing user (including users with no current domain access) to the Owner role. The exploit requires a single authenticated HTTP request and grants full domain ownership immediately, without any acceptance step from the target. This issue has been patched in version 1.25.0.
