GitHub CLI: Unescaped variable components in request URLs could allow path traversal

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

GitHub CLI (gh) is GitHub’s official command line tool. Prior to 2.97.0, some HTTP request URLs interpolate variable path components without percent encoding, allowing URL path metacharacters in attacker-controlled repository or resource values to make gh address a different API endpoint or resource than the user intended. This issue is fixed in version 2.97.0.

### Summary 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. ### Details 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. ### Impact 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. ### Remediation and Mitigation 1. Upgrade `gh` to `2.97.0`. 2. Be cautious when running `gh` against untrusted repositories or inputs whose names you do not control.
