CVE-2026-19539: CWE-862 Missing Authorization in Roskus Prospero Flow CRM
Authorization Bypass Through User-Controlled Key in the ticket management component in Roskus Prospero Flow CRM before 5.4.9 allows authenticated users of any company to read the full content (title, description, and attachments) of tickets belonging to another company, to hijack another company's tickets by reassigning their company_id, and to delete another company's tickets without any authorization check, via the ticket's numeric identifier, because the read and save operations retrieve the record without constraining the query to the authenticated user's company, and the delete controller type-hints a generic Illuminate\Http\Request instead of the TicketDeleteRequest that would enforce the required permission.
AI Analysis
Technical Summary
The vulnerability in Roskus Prospero Flow CRM before version 5.4.9 arises from improper authorization enforcement in the ticket management component. Authenticated users can bypass authorization controls by manipulating the ticket's numeric identifier (company_id). Read and save operations do not constrain queries to the user's company, allowing access to full ticket content (title, description, attachments) of other companies. The delete controller uses a generic request type instead of a specialized request that enforces permissions, enabling deletion of tickets from other companies without authorization. This is classified as CWE-862 (Missing Authorization).
Potential Impact
Exploitation of this vulnerability allows an authenticated user from one company to read sensitive ticket information, hijack tickets by changing their company association, and delete tickets belonging to other companies. This leads to unauthorized data disclosure, data integrity compromise, and potential denial of service for affected companies' ticket records.
Mitigation Recommendations
No official patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the ticket management component to trusted users and monitor for suspicious activity related to ticket access and modification.
