{"id":"CVE-2026-73232","summary":"ffuf denial of service (OOM) via HTTP response decompression bomb","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.","aliases":["GHSA-jcvh-xf52-2cwm"],"modified":"2026-08-14T03:51:53.693419730Z","published":"2026-08-11T19:32:48.560Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-409"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73232.json"},"references":[{"type":"WEB","url":"https://github.com/ffuf/ffuf/releases/tag/v2.2.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73232.json"},{"type":"ADVISORY","url":"https://github.com/ffuf/ffuf/security/advisories/GHSA-jcvh-xf52-2cwm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73232"},{"type":"FIX","url":"https://github.com/ffuf/ffuf/commit/fb0da86c60443b0dddbc9a86e91e3a6487dff79b"},{"type":"FIX","url":"https://github.com/ffuf/ffuf/pull/897"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ffuf/ffuf","events":[{"introduced":"0"},{"fixed":"fb0da86c60443b0dddbc9a86e91e3a6487dff79b"},{"fixed":"0aa36bcfa45c255f0d719f7d5bc58f7cc9c93659"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.2.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v2.1.0","v2.0.0","v1.5.0","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.2","v1.0.1","v1.0","v0.12","v0.11","v0.10","v0.9","v0.8","v0.7","v0.6","v0.5","v0.4","v0.3","v0.2","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
