Prior to 7.22, a remote unauthenticated attacker can exploit an HTTP/1.0 reverse-proxy deployment by sending a request with Transfer-Encoding: chunked and conflicting framing. The http_cb() function in src/http.c tests hm.proto.len with an impossible greater-than-eight condition even though mg_http_parse() requires an eight-byte protocol string, so is_http_1_0 is never set. Mongoose consequently processes chunked encoding that an HTTP/1.0 proxy can ignore, enabling request smuggling and unauthorized access or state changes. This issue is fixed in version 7.22.",null,[11],{"_key":12,"id":12,"name":13,"description":14,"type":15,"status":16,"abstraction":17,"likelihood_of_exploit":9,"capec":18},"CWE-444","Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')","The product acts as an intermediary HTTP agent\n         (such as a proxy or firewall) in the data flow between two\n         entities such as a client and server, but it does not\n         interpret malformed HTTP requests or responses in ways that\n         are consistent with how the messages will be processed by\n         those entities that are at the ultimate destination.","weakness","Incomplete","Base",[19,23],{"id":20,"name":21,"techniques":22},"CAPEC-273","HTTP Response Smuggling",[],{"id":24,"name":25,"techniques":26},"CAPEC-33","HTTP Request Smuggling",[],[],[],[],[],[],[],"2026-08-20T17:37:54.505Z","Received",{"cisa_kev":36,"cisa_ransomware":36,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":37,"severity_score":38,"severity_version":39,"severity_source":40,"severity_vector":41,"severity_status":34},false,"critical",9.1,"v3.1","cve.org","CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N",[43,49,54,58],{"url":44,"sources":45,"tags":47},"https://github.com/cesanta/mongoose/security/advisories/GHSA-mgp5-rjrv-h5j3",[40,46],"nvd",[48],"X Refsource CONFIRM",{"url":50,"sources":51,"tags":52},"https://github.com/cesanta/mongoose/pull/3611",[40,46],[53],"X Refsource MISC",{"url":55,"sources":56,"tags":57},"https://github.com/cesanta/mongoose/commit/a9df523f76f43a38bd53b4232b9cfd4c16869e71",[40,46],[53],{"url":59,"sources":60,"tags":61},"https://github.com/cesanta/mongoose/releases/tag/7.22",[40,46],[53],[],[],[65,70],{"source":40,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":66,"cvss_v4_0":9},{"baseScore":38,"baseSeverity":67,"vectorString":41,"impactScore":68,"exploitabilityScore":69},"CRITICAL",8.7,10,{"source":46,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":71,"cvss_v4_0":9},{"baseScore":38,"baseSeverity":67,"vectorString":41,"impactScore":68,"exploitabilityScore":69},[73],{"ecosystem":9,"name":74,"vendor":75,"product":74,"cpe_part":76,"purl_type":9,"purl_namespace":9,"purl_name":9,"source":9,"versions":77},"mongoose","cesanta","a",[78],{"version":79,"is_range":80,"range_type":40,"version_start":9,"version_start_type":9,"version_end":81,"version_end_type":82,"fixed_in":9},"\u003C 7.22",true,"7.22","excluding"]
