openhole-server vulnerable to path traversal via URL-decoded request path
CVE-2026-54650 · GHSA-fh2f-xfxc-q9cc
- Affected
- Go github.com/bablilayoub/openhole <= 0.1.1
- Fixed in
- 0.1.2· Vendor fix available
- Issue
- openhole-server forwarded the URL-decoded request path (r.URL.Path) to tunnel clients instead of the original request-target. Percent-encoded dot-segments (%2e) and separators (%2f) were decoded to ../ and / before reaching the local service. Go's ServeMux rejects literal ../ paths, but percent-encoded traversal sequences bypassed this and were delivered to backends as working path traversal. Impact An unauthenticated remote attacker could read files outside the published web root on tunneled local services that resolve paths without canonicalization. Example: - /%2e%2e/secret.txt → file outside web root - /%2e%2e/%2e%2e/etc/passwd → sensitive files Encoded slashes (/a%2fb) could also bypass path-based access controls. Fix v0.1.2 forwards r.URL.EscapedPath() on the server and preserves the request-target on the CLI client. Users should upgrade both openhole-server and the openhole CLI to v0.1.2 or later.
Recommended action: Upgrade to 0.1.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
