GHSA-GW25-M53R-QH88

SiYuan: path traversal via /export/temp/ short-circuit branch (incomplete fix for the export-disclosure hardening, GHSA-6865-qjcf-286f)

if strings.HasPrefix(c.Request.URL.Path, "/export/temp/") {
    c.File(filepath.Join(util.TempDir, c.Request.URL.Path))
    return
}

Authenticated arbitrary file read bypassing the sensitive-file protection: /etc/passwd, ~/.ssh/*, SiYuan
*.db workspace data, *.log.

Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

GHSA-GW25-M53R-QH88 has a CVSS score of 6.5 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.0.0-20260510110132-b763d787d1f2); upgrading removes the vulnerable code path.

• Apply IsSubPath + IsSensitivePath to the /export/temp/ branch (or restrict its root to TempDir/temp with
  an IsSubPath check).
• filepath.Clean the request path and reject ...
• Merge both branches into one guarded file-serving function.

1. What is GHSA-GW25-M53R-QH88? GHSA-GW25-M53R-QH88 is a medium-severity path traversal vulnerability in github.com/siyuan-note/siyuan/kernel (go), affecting versions < 0.0.0-20260510110132-b763d787d1f2. It is fixed in 0.0.0-20260510110132-b763d787d1f2. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
2. How severe is GHSA-GW25-M53R-QH88? GHSA-GW25-M53R-QH88 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/siyuan-note/siyuan/kernel are affected by GHSA-GW25-M53R-QH88? github.com/siyuan-note/siyuan/kernel (go) versions < 0.0.0-20260510110132-b763d787d1f2 is affected.
4. Is there a fix for GHSA-GW25-M53R-QH88? Yes. GHSA-GW25-M53R-QH88 is fixed in 0.0.0-20260510110132-b763d787d1f2. Upgrade to this version or later.
5. Is GHSA-GW25-M53R-QH88 exploitable, and should I be worried? Whether GHSA-GW25-M53R-QH88 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-GW25-M53R-QH88 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-GW25-M53R-QH88? Upgrade github.com/siyuan-note/siyuan/kernel to 0.0.0-20260510110132-b763d787d1f2 or later.
