Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ffuf是ffuf组织的一款Web模糊测试工具。 ffuf 2.2.0之前版本存在资源管理错误漏洞，该漏洞源于响应大小限制检查不充分，仅检查压缩的Content-Length，而io.ReadAll读取gzip、brotli、deflate等解压后响应体时未限制解压后大小，可能导致恶意目标服务器造成内存耗尽拒绝服务。

Vulnerability Title
ffuf denial of service (OOM) via HTTP response decompression bomb
Source: CVE Program / CVE List V5
Vulnerability Description
ffuf is a fast web fuzzer written in Go. Prior to 2.2.0, ffuf allows a malicious target server to cause an out-of-memory denial of service because the response size guard in pkg/runner/simple.go checks only the compressed Content-Length while io.ReadAll reads gzip, brotli, deflate, transparently decompressed, or chunked response bodies without a decompressed-size bound. This issue is fixed in version 2.2.0.
