CVE-2026-53470
Description
A flaw was found in migration-planner. An authenticated attacker could exploit an improper access control vulnerability in the /api/v1/sources/{id}/image-url endpoint.

Consequently, the attacker can download OVA images containing sensitive information, such as long-lived agent JSON Web Tokens (JWTs) and source configurations, potentially leading to unauthorized access and modification of the victim's source.
