{"id":"CVE-2026-44982","aliases":["GHSA-rw47-hm26-6wr7","GO-2026-5641"],"url":"https://o3.security/vulnerability/CVE-2026-44982","summary":"CrowdSec AppSec silently drops request body for chunked / HTTP-2 requests","details":"CrowdSec offers crowdsourced protection against malicious IPs. From 1.5.0 until 1.7.8, pkg/appsec/request.go NewParsedRequestFromRequest allocated a request body buffer from max(r.ContentLength, 0), so HTTP/1.1 requests using Transfer-Encoding: chunked and HTTP/2 requests without a content-length header produced an empty body and caused WAF rules targeting REQUEST_BODY, BODY_ARGS, ARGS_POST, JSON, or XML to be skipped. This issue is fixed in version 1.7.8.","published":"2026-07-16T19:50:26.067Z","modified":"2026-08-12T03:51:39.634703556Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},"epss":{"score":0.00372,"percentile":0.29958,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/crowdsecurity/crowdsec","fixedVersion":"1.7.8"}],"fix":{"url":"https://github.com/crowdsecurity/crowdsec/commit/3d5c4d9b127091e9063b9b5eb785372a599a4435","label":"crowdsecurity/crowdsec@3d5c4d9"},"references":[{"type":"WEB","url":"https://github.com/crowdsecurity/crowdsec/releases/tag/v1.7.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44982.json"},{"type":"ADVISORY","url":"https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-rw47-hm26-6wr7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44982"},{"type":"FIX","url":"https://github.com/crowdsecurity/crowdsec/commit/3d5c4d9b127091e9063b9b5eb785372a599a4435"},{"type":"FIX","url":"https://github.com/crowdsecurity/crowdsec/commit/57a793548671e6bbd2cde5562fe87b856ec9c642"},{"type":"FIX","url":"https://github.com/crowdsecurity/crowdsec/pull/4355"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.634703556Z"}}
