PraisonAI Platform before 0.1.9 Authorization Bypass via Label Endpoints

PraisonAI Platform before 0.1.9 fails to properly authorize label and issue-label mutations, allowing workspace members to rename and recolor shared labels and add or remove labels on owner-created issues. Attackers with workspace member privileges can exploit PATCH and POST/DELETE endpoints to alter shared label taxonomy and manipulate issue-label associations without owner or admin authorization.
