Attackers can request internal resources such as cloud instance metadata services or localhost-bound management interfaces, save the fetched response as a file in their own user folder, and retrieve it via the download endpoint to exfiltrate sensitive internal data or enumerate internal network hosts and ports.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},{"score":5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1793803693417,"publishedAt":1793803693417,"references":[{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/oqtane/oqtane.framework/releases/tag/v10.3.0"},{"source":"CNA: VulnCheck","tags":["release-notes"],"url":"https://www.oqtane.org/blog/!/160/oqtane-10-3-released"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/oqtane-framework-before-ssrf-via-file-upload-from-url"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
