CVE-2026-69084
CRITICALCVE-2026-69084 is a critical-severity (CVSS 10) SQL Injection vulnerability. O3 Security confirms whether CVE-2026-69084 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
SiYuan versions <= v3.7.2 expose the /api/search/searchEmbedBlock endpoint, which passes a client-supplied SQL statement verbatim to the main read-write siyuan.db handle with no single-statement, read-only, or admin restrictions. The endpoint is gated only by CheckAuth, making it reachable by the publish RoleReader token and by anonymous users when publish authentication is disabled. Because the underlying driver executes stacked statements, an attacker can read and modify content across all opened cleartext notebooks (encrypted per-box notebooks are excluded). Fixed in v3.7.3.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-69084 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-69084 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-69084. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
