Praisonai-Platform (<= 0.1.2)

An authorization bypass vulnerability exists in praisonai-platform where any member can remove any other member, including the workspace owner, due to missing role checks and owner protection logic, allowing an attacker to lock the legitimate owner out of their own workspace, leading to a permanent denial-of-service and potential workspace takeover (CVE-2026-47409).

PraisonAI Platform is vulnerable to cross-workspace IDOR and member-role privilege escalation, allowing unauthorized users to read, update, or delete resources across workspaces, escalate privileges, and potentially take over accounts and workspaces due to insufficient access controls and role enforcement.
