CVE-2026-69078Network attack vectorHinoki check available

SSRF and file disclosure via unrestricted PDF fetching

Published Aug 3, 2026 · Updated Aug 3, 2026

SSRF in CTI-Transmute 1.4.0 and earlier allows remote attackers to read local files and reach internal services through PDF reports. The evaluation renderer converts attacker-controlled conversion names, descriptions, and comments from Markdown to HTML, then lets WeasyPrint fetch file, HTTP, and HTTPS references without destination restrictions. Anonymous persisted conversions can reach this path; rendering a crafted report uses the server's filesystem and network privileges to retrieve data into the PDF.
