CVE-2026-78555Network attack vector

API key disclosure via hidden form fields

Published Aug 24, 2026 · Updated Aug 24, 2026

Credential exposure in RansomLook 2.0.0 and earlier allows remote authenticated users to recover complete API keys from an admin page. The /admin/apikeys handler passed each complete token to apikeys.html, which inserted it into hidden inputs for toggle and delete actions. Administrative access is required; viewing or retaining the response exposes credentials reusable with each key's assigned permissions.
