CVE-2026-78385Network attack vector

Authenticated SSRF and file read via PDF resources

Published Aug 24, 2026 · Updated Aug 24, 2026

SSRF in RansomLook 2.0.0 and earlier allows remote authenticated users to read server files or request network resources through PDF generation. Analysis Markdown is converted to HTML and passed to WeasyPrint without a restricted URL fetcher, so embedded file:// and http:// references are resolved by the server. An account permitted to create or modify an analysis must trigger PDF rendering; access is limited to files readable by the process and services reachable from its network context.
