What is CVE-2025-47870?

The Mattermost platform is susceptible to a security flaw in certain versions that results from the failure to properly sanitize the team invite ID in the POST /api/v4/teams/:teamId/restore endpoint. This oversight allows a team administrator, who does not possess member invite privileges, to access the sensitive team invite ID, potentially leading to unauthorized access or manipulation of team membership.

Affected Version(s)

Mattermost 10.8.0 <= 10.8.3

Mattermost 10.5.0 <= 10.5.8

Mattermost 9.11.0 <= 9.11.17
