FKIE_CVE-2026-40584
Vulnerability from fkie_nvd - Published: 2026-04-21 17:16 - Updated: 2026-06-17 10:45
Severity
Summary
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.
