  "details": "## Summary\n\n`Backpack\\CRUD\\Stats::makeCurlRequest` builds a shell command using unescaped input that originates from the HTTP `Host` header, then passes it to `exec()`. A specially crafted Host header can break out of the shell argument and cause the server to execute arbitrary OS commands as the web user.\n\nThe vulnerable code path is reached from `BackpackServiceProvider::boot()` on every HTTP request in production when `exec()` and `curl` are available. A 1-in-100 random gate is the only guard \u2014 an attacker can reliably trigger it by retrying.\n\n## Severity\n\n**High \u2014 CVSS 8.1**  \n`CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`\n\nAttack Complexity is rated **High** because default nginx and Apache configurations typically strip or reject malformed Host headers before they reach PHP, and `exec()` is often disabled for web processes in hardened environments. Both mitigations must be absent for exploitation.\n\n## Impact\n\nA successful exploit yields OS command execution as the web server user (`www-data`, `nginx`, etc.), giving an unauthenticated attacker access to environment secrets (APP_KEY, database credentials, API keys in `.env`), the filesystem, and any service the server can reach.\n\n## Fix\n\n`makeCurlRequest` was replaced with the Guzzle-based path already present in the codebase, eliminating the shell-command construction entirely. **Upgrade to a patched release immediately.**\n\n## Affected versions\n\n| Branch | Vulnerable range | First safe version |\n|--------|-----------------|-------------------|\n| 4.1.x  | `\u003c 4.1.70`      | 4.1.70            |\n| 5.x    | `\u003c 5.6.2`       | 5.6.2             |\n| 6.x    | `\u003c 6.8.13`      | 6.8.13            |\n| 7.x    | `\u003c 7.0.36`      | 7.0.36            |\n\n## Credits\n\nReported by Vishal Shukla ([@shukla304](https://github.com/shukla304)) via sechub.dev AI Agent.",
