Description
A flaw was found in migration-planner. An authenticated user can exploit this vulnerability by sending a DELETE request to the /api/v1/sources route, which lacks proper authorization and filtering. This allows for the destruction of all customer data, including sources, agents, and assessments, leading to a critical loss of availability and integrity across the entire SaaS platform.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/kubev2v/migration-planner, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/kubev2v/migration-planner to 0.13.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-53469 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
