This\ncould allow for Waitress to treat a single request as multiple requests\nin the case of HTTP pipelining (CVE-2019-16786).\n\nIn Waitress through version 1.4.0, if a proxy server is used in front of\nwaitress, an invalid request may be sent by an attacker that bypasses the\nfront-end and is parsed differently by waitress leading to a potential for\nHTTP request smuggling. If a front-end server does HTTP pipelining to a\nbackend Waitress server this could lead to HTTP request splitting which\nmay lead to potential cache poisoning or unexpected information disclosure\n(CVE-2019-16789).\n",null,[],[],[],[14,16,18],{"_key":15},"CVE-2019-16785",{"_key":17},"CVE-2019-16786",{"_key":19},"CVE-2019-16789",[],[],[23,24,25],{"_key":15},{"_key":17},{"_key":19},"2020-02-13T10:49:00Z","2026-04-16T04:26:02.734439Z",{"cisa_kev":29,"cisa_ransomware":29,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[31,37,42],{"url":32,"sources":33,"tags":35},"https://advisories.mageia.org/MGASA-2020-0083.html",[34],"osv_mageia",[36],"Advisory",{"url":38,"sources":39,"tags":40},"https://bugs.mageia.org/show_bug.cgi?id=26014",[34],[41],"REPORT",{"url":43,"sources":44,"tags":45},"https://docs.pylonsproject.org/projects/waitress/en/latest/#security-fixes",[34],[41,46],"WEB",[],[],[],[51],{"ecosystem":52,"name":53,"vendor":54,"product":53,"cpe_part":9,"purl_type":55,"purl_namespace":54,"purl_name":53,"source":9,"versions":56},"Mageia","python-waitress","mageia","rpm",[57],{"version":58,"is_range":59,"range_type":60,"version_start":9,"version_start_type":9,"version_end":61,"version_end_type":62,"fixed_in":9},"lt1_4_2_1_mga7",true,"ecosystem","1.4.2-1.mga7","excluding"]
