CVE-2026-73232

ffuf denial of service (OOM) via HTTP response decompression bomb

Published Aug 11, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
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.
