HighCVSS 8.7Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
Missing Authorization in the permission management component in Roskus Prospero Flow CRM before 5.2.1 allows any authenticated user to grant any role, including their own, the complete set of application permissions via a crafted POST request to the permission save endpoint, which performs no authorization check before synchronizing the submitted permissions to the specified role.
Risk Assessment
An authenticated user can escalate their privileges to full access, potentially leading to confidentiality and integrity breaches.
Recommendation
Update Prospero Flow CRM to version 5.2.1 or later. Implement authorization checks on the permission save endpoint so only authorized administrators can modify roles.
