CVE-2026-50888Network attack vector

Internal network scanning via crafted scraper URL

Published Jun 15, 2026 · Updated Jun 15, 2026

Server-side request forgery in Koillection 1.8.0 allows remote authenticated users to scan internal resources through a crafted scraper URL. The custom scraper accepts an attacker-controlled destination and makes the corresponding server-side request without blocking internal targets. Exploitation requires a valid account, and the established consequence is internal-resource discovery rather than confirmed data retrieval or modification.
