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.","epss":{"date":"2026-11-08","percentile":0.34276,"score":0.00398},"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},{"score":4,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1794146450722,"publishedAt":1791983700461,"references":[{"source":"CNA: VulnCheck","tags":["patch","release-notes"],"url":"https://github.com/ONLYOFFICE/DocumentServer/releases/tag/v10.0.0"},{"source":"CNA: VulnCheck","tags":["issue-tracking","release-notes"],"url":"https://github.com/ONLYOFFICE/DocumentServer/blob/master/CHANGELOG.md#1000"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/onlyoffice-documentserver-before-ssrf-via-downloadfile-isinjwttoken-bypass"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
