CVE-2026-110652 · ONLYOFFICE DocumentServer before 10.0.0 SSRF via downloadfile isInJwtToken Bypass
This page contains facts from public vulnerability sources. Check the original advisory before updating.
ONLYOFFICE DocumentServer before 10.0.0 contains an unauthenticated server-side request forgery vulnerability in the /downloadfile/:docid endpoint that allows remote attackers to bypass the private-IP request-filtering-agent by exploiting the isInJwtToken flag when JWT verification is disabled in the default configuration. Attackers can submit a crafted request body containing an internal or loopback URL, which is treated as a DIRECT request skipping private-address filtering, causing the server to fetch and proxy back arbitrary private-network and cloud metadata content.
