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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-693"],"references":["https://github.com/crowdsecurity/crowdsec/commit/3d5c4d9b127091e9063b9b5eb785372a599a4435","https://github.com/crowdsecurity/crowdsec/commit/57a793548671e6bbd2cde5562fe87b856ec9c642","https://github.com/crowdsecurity/crowdsec/pull/4355","https://github.com/crowdsecurity/crowdsec/releases/tag/v1.7.8","https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-rw47-hm26-6wr7"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-44982","score":0.00372,"percentile":0.30907,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rw47-hm26-6wr7","url":"https://osv.dev/vulnerability/GHSA-rw47-hm26-6wr7","summary":"CrowdSec AppSec silently drops request body for chunked / HTTP-2 requests","modified":"2026-06-25T23:11:30.642912402Z","packages":[{"ecosystem":"Go","name":"github.com/crowdsecurity/crowdsec","purl":"pkg:golang/github.com/crowdsecurity/crowdsec","ranges":[">=1.5.0 <1.7.8"],"fixed":["1.7.8"]}]},{"id":"GO-2026-5641","url":"https://osv.dev/vulnerability/GO-2026-5641","summary":"CrowdSec AppSec silently drops request body for chunked / HTTP-2 requests in github.com/crowdsecurity/crowdsec","modified":"2026-06-25T23:01:37.452965870Z","packages":[{"ecosystem":"Go","name":"github.com/crowdsecurity/crowdsec","purl":"pkg:golang/github.com/crowdsecurity/crowdsec","ranges":[">=1.5.0 <1.7.8"],"fixed":["1.7.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
