CVE-2026-68585
CVE-2026-68585 is a CWE-862 vulnerability in github.com/siyuan-note/siyuan/kernel. O3 Security confirms whether CVE-2026-68585 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
SiYuan before v3.7.3 Metadata Disclosure via getBlockInfo
Real-World Exposure
github.com/siyuan-note/siyuan/kernelReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
SiYuan versions before v3.7.3 contain a metadata disclosure vulnerability in the /api/block/getBlockInfo endpoint that returns document root metadata including title for publish-forbidden documents without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a block ID to retrieve the title, notebook, path, root ID, and icon of documents administrators marked as excluded from publishing.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/siyuan-note/siyuan/kernel. 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.
Fix
Update github.com/siyuan-note/siyuan/kernel to 0.0.0-20260721014951-ffde3b21eca4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-68585 is resolved across your whole dependency graph.
Workarounds
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-2026-68585 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-2026-68585. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-68585 in your dependencies?
O3 detects CVE-2026-68585 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
