Insufficient Authorization Enforcement in Project Management Routes

PraisonAI Platform (praisonai-platform) before 0.1.9 fails to enforce owner/admin authorization on the PATCH routes for projects, issues, and agents, which only require workspace-member role. A workspace member can modify owner-created records; for projects, a member can reassign lead_id to their own user id and then delete the owner-created project, bypassing the delete route's owner/admin permission check.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-61442 represents a critical authorization bypass vulnerability in PraisonAI Platform where PATCH operations on projects, issues, and agents fail to properly enforce owner and admin role restrictions. The vulnerability allows workspace members with basic membership privileges to modify records created by owners, including reassigning project leadership and subsequently deleting owner-created projects through privilege escalation. This impacts any organization using PraisonAI Platform versions before 0.1.9, where multi-tenant workspace environments rely on role-based access controls that are incompletely implemented. The attack is particularly dangerous because it chains a seemingly benign permission (reassigning lead_id) with an otherwise-protected destructive action (deletion), effectively bypassing the intended authorization model.

Casky's 283 matching skills detect this vulnerability pattern by mapping it to MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access), using Claude AI's extended reasoning to correlate authorization enforcement gaps across API endpoints. Practitioners using Casky would identify findings showing: (1) insufficient role validation on PATCH routes where only workspace-member checks occur rather than owner/admin validation, (2) permission-check bypass chains where intermediate operations (reassigning ownership) enable otherwise-blocked actions (deletion), and (3) authorization inconsistency between related endpoints (PATCH allows modification but DELETE requires stricter controls). The platform's multi-layered skill evaluation would flag this as a Privilege Escalation path, helping security teams prioritize upgrades and implement compensating controls like API request logging and role-based endpoint monitoring.
