Quick assessment

Affected
cli cli
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GitHub CLI是GitHub CLI组织开源的一款命令行界面工具。 GitHub CLI 2.97.0之前版本存在路径遍历漏洞，该漏洞源于HTTP请求URL在插入可变路径组件时未进行百分号编码，攻击者控制的仓库或资源值中的URL路径元字符可能使gh访问非预期的API端点或资源。

Vulnerability Title
GitHub CLI: Unescaped variable components in request URLs could allow path traversal
Source: CVE Program / CVE List V5
Vulnerability Description
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.
