CVE-2026-72924
Description
A flaw was found in GitHub CLI. The gh codespace ports forward command, by default, exposes forwarded services on all local network interfaces. This allows a network-adjacent attacker to access these services through the user's machine while port forwarding is active, even if the original Codespaces port is private. This can lead to unauthorized access to internal services.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
