CVE-2026-78386Network attack vector

Unauthenticated scraping credential disclosure via public APIs

Published Aug 24, 2026 · Updated Aug 24, 2026

Information disclosure in RansomLook 2.0.0 and earlier allows remote attackers to read scraping credentials and configuration through public APIs. Public group and market handlers returned non-private location records without restricting output to public fields, exposing header, init_script, and browser data. No authentication is required; disclosed headers or cookies expose monitored-site sessions, while scripts and browser details reveal collection and bypass logic.
