SQL Injection via Malicious RVTools Spreadsheet Upload

A flaw was found in migration-planner. A remote authenticated attacker could exploit this vulnerability by uploading a specially crafted RVTools .xlsx file. Due to improper input sanitization, malicious SQL embedded within a spreadsheet cell is executed when cluster names are processed. This SQL Injection allows for arbitrary file reading on the system, potentially exposing sensitive information such as Kubernetes service account tokens and other credentials, which could lead to a full compromise of the SaaS environment.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-53474 represents a critical SQL injection vulnerability in migration-planner that exploits improper input sanitization during RVTools .xlsx file processing. Remote authenticated attackers can embed malicious SQL commands within spreadsheet cells, which execute when the application processes cluster names. This vulnerability is particularly severe because it enables arbitrary file reading on affected systems, potentially exposing highly sensitive credentials including Kubernetes service account tokens, database passwords, and API keys. Organizations using migration-planner for infrastructure assessment and planning face immediate risk of credential compromise and subsequent lateral movement within their cloud and on-premises environments.

Casky's 301 matched security skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this CVE across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance via resource development). Practitioners using Casky would identify detection opportunities at multiple stages: initial file upload anomalies showing crafted .xlsx payloads with embedded SQL syntax in cell values, SQL execution patterns deviating from normal cluster name processing workflows, and suspicious file access attempts targeting credential storage locations. The platform's skill mapping would highlight lateral movement indicators following successful exploitation—unauthorized reads of service account tokens and subsequent authentication attempts using harvested credentials—enabling teams to correlate upload activities with downstream access patterns and contain compromises before attackers establish persistence or move across cluster boundaries.
