Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-19539 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-19539 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-19539. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
