CVE-2026-54650: openhole-server vulnerable to path traversal via URL-decoded request path

• Severity: high (CVSS 8.6 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-28 · updated 2026-10-23
• Weakness: CWE-22

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.
