How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-54650, inspect your project dependencies for Github.com/bablilayoub/openhole:

inspect dependencies for github.com/bablilayoub/openhole

Analyze the terminal output to locate any version of Github.com/bablilayoub/openhole in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/bablilayoub/openhole, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary 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.
