Attackers can craft malicious webpages that establish WebSocket connections to this endpoint and direct the SiYuan kernel process to proxy arbitrary network traffic to attacker-chosen targets, enabling authenticated network pivoting through the victim's machine.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N","score":7.1,"severity":null}],"references":["https://github.com/siyuan-note/siyuan/security/advisories/GHSA-3cc2-h3v6-rqpq","https://www.vulncheck.com/advisories/siyuan-cross-site-websocket-hijacking-via-network-proxy"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-60085","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 17, 2026, 11:04:37 AM","dateUpdated":"Aug 28, 2026, 1:45:55 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
