What is CVE-2026-54650?
CVE-2026-54650 is a high-severity path traversal vulnerability in bablilayoub openhole, published on 28 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-22
