Privilege Escalation via Incorrect Authorization in SOPlanning

SOPlanning is vulnerable to Privilege Escalation in user management tab. Users with user_manage_team role are allowed to modify permissions of users. However, they are able to assign administrative permissions to any user including themselves. This allow a malicious authenticated attacker with this role to escalate to admin privileges. This issue affects both Bulk Update functionality and regular edition of user's right and privileges. This issue was fixed in version 1.55.
