Network-adjacent attackers can sniff the cleartext login flow and session cookie, which lacks the Secure attribute while responses omit HSTS, to hijack kernel API sessions.","categories":["Unclassified"],"product":"siyuan","vendor":"siyuan-note","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116166","source_modified_at":"2026-10-25T13:20:09.700Z","fetched_at":"2026-10-25T16:01:37.004770Z","product":"siyuan","vendor":"siyuan-note","versions":[{"version":"3.6.0","status":"affected","versionType":"semver","lessThan":"3.8.7"},{"version":"3.8.7","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116166","source_modified_at":"2026-10-25T13:20:09.700Z","fetched_at":"2026-10-25T16:01:37.004770Z","package":{"name":"siyuan","ecosystem":null},"version":"3.8.7","basis":"first unaffected version stated in the CVE record"}],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-25T13:20:09.700Z","modified_at":"2026-10-25T13:20:09.700Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116166","fetched_at":"2026-10-25T16:01:37.004770Z","source_modified_at":"2026-10-25T13:20:09.700Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-hpj5-f7cj-vvwr","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/siyuan-3.6.0-before-3.8.7-cleartext-transmission-via-unenforced-networkservetls-setting","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-25T13:20:09.700Z","content_hash":"72dbb9746609de1c9548d90b03222b69d4dc79c10d0ec5c3090a913ef8eff892"}}
