Overview
Affected versions of this package are vulnerable to Missing Authorization in the Team API endpoints due to improper authorization checks in the TeamController process. An attacker can gain unauthorized access to modify any team's membership, customer assignments, project assignments, and activity assignments by sending crafted API requests with sufficient permissions. This is only exploitable if an administrator assigns the edit_team permission to a lower-privilege role, such as ROLE_TEAMLEAD, through the permissions UI.
