CVE-2026-40584

HIGH

RansomLook - Improper Filtering of Private Location Entries in API Endpoints Leads to Information Exposure

Title source: cna
STIX 2.1

Description

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.
