CVE-2025-55294

描述

## Impact This vulnerability is a **command injection** issue. When user-controlled input is passed into the `format` option of the screenshot function, it is interpolated into a shell command without sanitization. An attacker can craft malicious input such as: { format: "; echo vulnerable > /tmp/hello;" } This results in arbitrary command execution with the privileges of the calling process. **Who is impacted:** Any application that accepts untrusted input and forwards it directly (or indirectly) into the `format` option is affected. If the library is used in a server-side context (e.g., API endpoints, web services), attackers may be able to exploit this **remotely and without authentication**, leading to full compromise of confidentiality, integrity, and availability. **CVSS v3.1 Base Score:** 9.8 (Critical) `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H` ## Patches The issue has been patched in **version 1.15.2**. All users are strongly recommended to upgrade to **1.15.2 or later**. All earlier versions are vulnerable. ## Workarounds If upgrading is not immediately possible, developers should: - **Strictly validate or whitelist** acceptable `format` values (e.g., `"jpeg"`, `"png"`, `"webp"`). - **Reject or sanitize** any unexpected input before passing it to the library. - Avoid allowing user-controlled data to reach the `format` option. ## References - [CWE-78: OS Command Injection](https://cwe.mitre.org/data/definitions/78.html) - [OWASP: Command Injection](https://owasp.org/www-community/attacks/Command_Injection)
