{"id":"GHSA-p8cp-78hp-wmq8","summary":"Duplicate Advisory: SQL injection in backlink/mention search via unescaped stored and client input (publish mode): first-order (client keyword) and second-order (stored document title) breakout on read-write handle","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-q2vg-7qgx-x5fc. This link is maintained to preserve external references.\n\n## Original Description\nSiYuan versions \u003c= v3.7.2 contain a SQL injection vulnerability in the backlink/mention search query (kernel/model/backlink.go), which concatenates stored block metadata (title, name, alias, anchor text) and the client-supplied keyword into a SQL MATCH/search statement while escaping only the double-quote character and not the single quote. A single quote in the client keyword (first-order, reachable by an anonymous or RoleReader user on the publish surface) or in stored document metadata (second-order) breaks out of the string literal. Because the query runs on the main read-write siyuan.db handle via a statement-stacking-capable driver, an attacker can execute arbitrary SQL, enabling cross-notebook read and write. Fixed in v3.7.4.","modified":"2026-09-03T22:30:08.607985183Z","published":"2026-08-14T12:31:24Z","withdrawn":"2026-09-03T22:24:31Z","database_specific":{"nvd_published_at":"2026-08-14T12:16:43Z","cwe_ids":["CWE-89"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-09-03T22:24:31Z"},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-q2vg-7qgx-x5fc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72811"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-sql-injection-via-backlink-search"}],"affected":[{"package":{"name":"github.com/siyuan-note/siyuan/kernel","ecosystem":"Go","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c 3.7.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-p8cp-78hp-wmq8/GHSA-p8cp-78hp-wmq8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
