HIGH 8.6REMOTE
CVE-2026-54650 is a high-severity flaw (CVSS 8.6) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
openhole exposes localhost to the internet in one command. In 0.1.1 and earlier, openhole-server in internal/server/public_proxy.go forwarded r.URL.Path instead of preserving the original request target with r.URL.EscapedPath(), allowing percent encoded dot segments %2e and separators %2f to reach tunneled local services as ../ and / for path traversal. This issue is fixed in version 0.1.2.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
