Background
Superagent is an npm package that provides a high-level HTTP request library for Node.js. It allows developers to make HTTP requests and handle responses easily. However, versions of superagent prior to 3.7.0 are vulnerable to a Denial of Service (DoS) attack due to a lack of post-decompression size checking of ZIP compressed HTTP responses. This vulnerability can be exploited by a ZIP bomb attack, where a small ZIP file can consume excessive CPU, memory, and disk resources when decompressed.
Vulnerability Detail
The vulnerability in superagent arises from the failure to validate the post-decompression size of ZIP compressed HTTP responses. This allows an attacker to send a malicious ZIP file that, when decompressed, expands to a significantly larger size than the original file. As a result, the system may experience unrestrained consumption of CPU, memory, and disk resources, leading to a DoS condition. This vulnerability has a low severity rating and is identified by the Common Weakness Enumeration (CWE) IDs: CWE-400 and CWE-409.
