A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 2.97.0
Patched in 2.97.0
Details
A path traversal vulnerability has been identified in the GitHub CLI where some HTTP request URLs, REST API calls in particular, were built without properly escaping their variable path components. A value containing URL path metacharacters can alter the request path and cause gh to address a different resource than intended.
Not all request URLs in the codebase were built with proper escaping of their variable path components. When a component is interpolated into the path without percent encoding, and that component contains URL path metacharacters, it breaks out of its intended segment and changes the effective request path.
In 2.97.0, request URLs are constructed in a safe manner, so a variable component can no longer escape its intended segment.
An attacker who can control a value that flows into a request path can cause gh to send the request to a different API endpoint than intended. This can lead the CLI to read or act on a resource other than the one the user meant to target.
