⚠️ Risk & Real-World Impact
Worst Case
Unauthorized users could automate malicious workflow actions, potentially leading to data manipulation, privilege escalation, or disruption of normal operations.
Likely Case
Users with limited permissions could inadvertently or intentionally automate workflow actions they shouldn't control, causing operational issues or minor data integrity problems.
If Mitigated
With proper permission controls and monitoring, impact would be limited to minor configuration changes that could be quickly detected and reverted.
🎯 Exploit Status
Exploitation requires authenticated access but not necessarily administrative privileges. The vulnerability is in the permission validation logic.
