CVE-2026-54650

bablilayoub openhole

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.
