Anonymous attackers can retrieve full content of password-protected documents by obtaining internal block IDs from reader-accessible endpoints and calling unprotected content endpoints to bypass the password gate.","state":0,"publishedAt":"2026-08-03T13:20:36.458+00:00","modifiedAt":"2026-08-14T16:51:06.898+00:00","affected":[{"ecosystem":"Vendor product","name":"siyuan","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"siyuan-note\",\n                    \"product\": \"siyuan\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:golang/github.com/siyuan-note/siyuan/kernel\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.7.3\"\n                        },\n                        {\n                            \"version\": \"3.7.3\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","score":9.2,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6,"severity":"HIGH"}],"references":["https://github.com/siyuan-note/siyuan/security/advisories/GHSA-7j72-f6wg-cxw6","https://www.vulncheck.com/advisories/siyuan-before-authentication-bypass-via-content-endpoints"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-68584","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-68584","identifiers":["CVE-2026-68584"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
