SQL Injection in migration-planner Allows File Reading and Environment Compromise.

CVE advisorySeverity: MEDIUM (CVSS 6.5)

CVE-2026-53474

The vulnerability exists in a migration-planner tool used to process RVTools files. While it requires an authenticated user to upload files, such tools are often used in administrative or migration contexts that may be accessible via web interfaces. However, it is not a standard internet-facing edge service or public portal, making internet exposure possible but not the default design.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in migration-planner, allowing authenticated attackers to execute malicious SQL commands by uploading a specially crafted RVTools spreadsheet. This could lead to the exposure of sensitive credentials and compromise the entire SaaS environment.

Attackers can inject malicious code via spreadsheets.
Sensitive credentials could be exposed by exploitation.
Assess tool usage and potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker who has already gained authenticated access can upload a malicious `.xlsx` file to the migration-planner. This file contains embedded SQL code in its spreadsheet cells. When the application processes cluster names from this file, it fails to properly sanitize the input, leading to the execution of the embedded SQL code. This vulnerability can then be leveraged to read arbitrary files from the system, potentially leading to a complete compromise of the SaaS environment.

Live Threat

Current exploitation, exposure, and threat context

A remote authenticated attacker can exploit this vulnerability by uploading a malicious RVTools .xlsx file. When cluster names are processed, SQL injection within a spreadsheet cell can execute, allowing arbitrary file reading on the system. This could expose sensitive information like Kubernetes service account tokens and other credentials, potentially leading to a full compromise of the SaaS environment.

Sensitive system and user credentials.
Upload malicious file to trigger SQL injection.
Full SaaS environment compromise.

Operational Fix

Recommended remediation, mitigation, and detection steps

This critical vulnerability in migration-planner requires immediate attention from teams managing SaaS environments and infrastructure. Exploitation of this SQL injection flaw allows remote authenticated attackers to read arbitrary files, potentially leading to a full compromise of sensitive credentials and the entire SaaS environment. The first practical step is to identify all instances of migration-planner, confirm their accessibility and business criticality, and identify the accountable owner for remediation planning.

Application and Platform teams own the issue.
Verify migration-planner instances and reachability.
Plan remediation based on verified risk.

Frequently asked questions

What is migration-planner and how is it used?

migration-planner is a specialized tool designed to assist in infrastructure transitions, specifically by processing RVTools data. It helps technical teams analyze virtualized environments by importing .xlsx spreadsheet exports, which the software then parses to map out cluster configurations and resource inventories for migration planning.

What does CVE-2026-53474 mean in plain English?

This is a SQL Injection vulnerability (CWE-89). It occurs when the software fails to properly sanitize input from uploaded spreadsheet files. Because the application treats text inside a spreadsheet cell as a command, an attacker can insert malicious SQL code that the system then executes, allowing them to read sensitive files from the underlying server.

How is this SQL injection triggered?

The vulnerability is triggered when a user uploads a specially crafted RVTools .xlsx file containing malicious SQL commands within a cluster name cell. Simply having the file on your system or interacting with the tool without performing this specific upload does not activate the flaw; the application must actively process the malicious input.

Is my migration-planner instance at risk?

According to Halo Surface Signal, this vulnerability is not typically found in public-facing edge services, but it is often accessible via internal administrative web interfaces. You should consider your instance at risk if it is reachable by any authenticated user who has the capability to upload migration files.

What are the first steps to address this issue?

Start by identifying all active instances of migration-planner within your infrastructure. Once you have a complete list, verify which teams own or manage these deployments. Finally, confirm the accessibility of these tools and coordinate with the relevant platform owners to prioritize remediation and monitor for updates.
