CVE-2026-53474: Openshift Migration Advisor: Improper input sanitization allows specially crafted RVTools .xlsx files to include malicious SQL commands

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• 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.
• Needs an account (low (any account)). Exposure depends on who can log in.
• 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. 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.
