{"id":"UBUNTU-CVE-2026-44982","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.","modified":"2026-07-29T07:57:02Z","published":"2026-07-16T20:16:00Z","upstream":["CVE-2026-44982"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-44982"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-44982"},{"type":"REPORT","url":"https://github.com/crowdsecurity/crowdsec/commit/3d5c4d9b127091e9063b9b5eb785372a599a4435"},{"type":"REPORT","url":"https://github.com/crowdsecurity/crowdsec/commit/57a793548671e6bbd2cde5562fe87b856ec9c642"},{"type":"REPORT","url":"https://github.com/crowdsecurity/crowdsec/pull/4355"},{"type":"REPORT","url":"https://github.com/crowdsecurity/crowdsec/releases/tag/v1.7.8"},{"type":"REPORT","url":"https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-rw47-hm26-6wr7"}],"affected":[{"package":{"name":"crowdsec","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/crowdsec?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.6-6build1","1.4.6-6ubuntu0.24.04.1","1.4.6-6ubuntu0.24.04.1+esm1","1.4.6-6ubuntu0.24.04.1+esm2","1.4.6-6ubuntu0.24.04.2","1.4.6-6ubuntu0.24.04.2+esm1","1.4.6-6ubuntu0.24.04.2+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"crowdsec","binary_version":"1.4.6-6ubuntu0.24.04.2+esm2"},{"binary_name":"golang-github-crowdsecurity-crowdsec-dev","binary_version":"1.4.6-6ubuntu0.24.04.2+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44982.json"}},{"package":{"name":"crowdsec","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/crowdsec?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.6-10","1.4.6-10.1","1.4.6-10.1ubuntu0.26.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"crowdsec","binary_version":"1.4.6-10.1ubuntu0.26.04.1~esm1"},{"binary_version":"1.4.6-10.1ubuntu0.26.04.1~esm1","binary_name":"golang-github-crowdsecurity-crowdsec-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44982.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
