{"id":"UBUNTU-CVE-2026-73232","details":"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.","modified":"2026-08-19T11:11:14Z","published":"2026-08-11T20:18:00Z","upstream":["CVE-2026-73232"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-73232"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-73232"},{"type":"REPORT","url":"https://github.com/ffuf/ffuf/security/advisories/GHSA-jcvh-xf52-2cwm"},{"type":"REPORT","url":"https://github.com/ffuf/ffuf/pull/897"},{"type":"REPORT","url":"https://github.com/ffuf/ffuf/commit/fb0da86c60443b0dddbc9a86e91e3a6487dff79b"},{"type":"REPORT","url":"https://github.com/ffuf/ffuf/releases/tag/v2.2.0"}],"affected":[{"package":{"name":"ffuf","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/ffuf?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.0-1","binary_name":"ffuf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73232.json"}},{"package":{"name":"ffuf","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/ffuf?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0-1build1","2.1.0-1","2.1.0-1ubuntu0.24.04.1","2.1.0-1ubuntu0.24.04.2","2.1.0-1ubuntu0.24.04.2+esm1","2.1.0-1ubuntu0.24.04.3","2.1.0-1ubuntu0.24.04.3+esm1","2.1.0-1ubuntu0.24.04.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"ffuf","binary_version":"2.1.0-1ubuntu0.24.04.3+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73232.json"}},{"package":{"name":"ffuf","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/ffuf?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0-1","2.1.0-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.1.0-1build1","binary_name":"ffuf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-73232.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
