Description
Dragonfly is an open source P2P-based file distribution and image acceleration system. In versions 2.4.1-rc.0 and below, the Job API endpoints (/api/v1/jobs) lack JWT authentication middleware and RBAC authorization checks in the routing configuration. This allows any unauthenticated user with access to the Manager API to view, update and delete jobs. The issue is fixed in version 2.4.1-rc.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for d7y.io/dragonfly/v2. 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.
Fix
Update d7y.io/dragonfly/v2 to 2.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-24124 is resolved across your whole dependency graph.
Workarounds
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-2026-24124 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-2026-24124. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
