La Suite Docs through 6.0.0 contains an authorization bypass vulnerability that allows authenticated users to write comments into threads of documents they cannot access. Attackers who know a thread UUID can route a POST comment request through their own document's resourceid, inserting comments into another document's thread without access.

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.
