CVE-2026-40584 · Severity: high · CVSS 7.5 · Published 2026-04-21

RansomLook is a tool to monitor Ransomware groups and markets and extract their victims. Prior to 1.9.0, the API in the affected application improperly filters private location entries in website/web/api/genericapi.py. Because the code removes elements from a list while iterating over it, entries marked as private may be unintentionally retained in API responses, allowing unauthorized disclosure of non-public location information. This vulnerability is fixed in 1.9.0.
