CVE-2025-67488
HIGHCVE-2025-67488 is a high-severity (CVSS 7.8) Path Traversal vulnerability in github.com/siyuan-note/siyuan/kernel. O3 Security confirms whether CVE-2025-67488 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
SiYuan: ZipSlip -> Arbitrary File Overwrite -> RCE
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 is self-hosted, open source personal knowledge management software. Versions 0.0.0-20251202123337-6ef83b42c7ce and below contain function importZipMd which is vulnerable to ZipSlips, allowing an authenticated user to overwrite files on the system. An authenticated user with access to the import functionality in notes is able to overwrite any file on the system, and can escalate to full code execution under some circumstances. A fix is planned for version 3.5.0.

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.
Remediation status
No patched version of github.com/siyuan-note/siyuan/kernel has shipped for CVE-2025-67488 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-2025-67488 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-2025-67488. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
