Summary
A flaw was found in migration-planner that allows an authenticated attacker to bypass access control in the `/api/v1/sources/{id}/image-url` endpoint. This flaw enables the attacker to obtain presigned S3 URLs for OVA images belonging to other users.
Risk Assessment
This vulnerability may lead to the download of OVA images containing sensitive information, posing a risk of unauthorized access and modification of the victim's sources.
Recommendation
It is recommended to implement proper access controls on the endpoint to prevent unauthorized access to user resources.
Other vulnerabilities in migration-planner
See all- CVE-2026-53474Critical
A flaw was found in migration-planner that allows a remote authenticated attacker to upload a specially crafted RVTools .xlsx file. Due to improper input sanitization, malicious SQL embedded within spreadsheet cells is executed when processing cluster names.
- CVE-2026-53471Critical
A flaw exists in the migration-planner where the agent-API middleware fails to properly validate the source_id claim in JWTs. This allows an authenticated attacker to manipulate data across different tenants, leading to a complete collapse of tenant isolation.
- CVE-2026-53469Critical
A flaw was found in migration-planner that allows an authenticated user to send a DELETE request to the /api/v1/sources route, which lacks proper authorization and filtering. This enables the destruction of all customer data, including sources, agents, and assessments.
- CVE-2026-53472Medium
A flaw in migration-planner. Insufficient validation of the AgentStatusUpdate.CredentialUrl field allows an authenticated attacker to store a malicious javascript: URL. When a victim views this URL in the Hybrid Cloud Console, it can lead to Cross-Site Scripting (XSS), enabling script execution in the victim's session and potentially disclosing sensitive information.
Original NVD description (English source)
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. This flaw allows the attacker to bypass an ownership check and obtain presigned S3 URLs for Open Virtual Appliance (OVA) images belonging to other users. 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.
