{"id":"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.","aliases":["GHSA-rw47-hm26-6wr7","GO-2026-5641"],"modified":"2026-08-12T03:51:39.634703556Z","published":"2026-07-16T19:50:26.067Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-693"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44982.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/crowdsecurity/crowdsec","events":[{"introduced":"712a2d1db00309915fcaf3e72189c1a74702b96c"},{"fixed":"3d5c4d9b127091e9063b9b5eb785372a599a4435"},{"fixed":"57a793548671e6bbd2cde5562fe87b856ec9c642"},{"fixed":"632274597a88a6b01ed41c0e6affca0f87ff26df"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"1.5.0"},{"fixed":"1.7.8"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44982.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"}]}
