# CVE-2026-53469: Openshift Migration Advisor lacks proper authorization and filtering for its DELETE /api/v1/sources API

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5% , percentile 43: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 43% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/kubev2v/migration-planner (Go) < 0.13.5, fixed in 0.13.5 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- Go `github.com/kubev2v/migration-planner` < 0.13.5 → fixed: 0.13.5

## Affected products (CVE record)

-  migration-planner: < 0.13.5

## Severity

- redhat CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.51% probability of exploitation activity in the next 30 days; percentile 43.
