{"id":"UBUNTU-CVE-2026-116130","details":"HTTP::Parser::XS versions before 0.18 for Perl truncate PATH_INFO at an encoded NUL byte in parse_http_request. The XS parser URL-decodes the request path and measures the result with strlen(), so PATH_INFO ends at the first byte decoded from %00. The pure-Perl backend is not affected. A remote attacker can send a path that a proxy or filter checks in full while the application routes on a shorter one.","modified":"2026-11-04T03:30:26.262212453Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-116130"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116130"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116130"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/44760361/"},{"type":"REPORT","url":"https://github.com/kazuho/p5-http-parser-xs/commit/f388b9d7994722b01edd03d57de7d2fb819e1aae.patch"},{"type":"REPORT","url":"https://metacpan.org/release/KAZUHO/HTTP-Parser-XS-0.18/changes"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/10/30/12"}],"affected":[{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-1","0.17-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-1build4","0.17-1build5"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-1build5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-2","0.17-2build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-2build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-2build2","0.17-2build3","0.17-2build4","0.17-2build5"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-2build5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-2build6","0.17-2build7"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-2build7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}},{"package":{"name":"libhttp-parser-xs-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libhttp-parser-xs-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17-2build6"],"ecosystem_specific":{"binaries":[{"binary_name":"libhttp-parser-xs-perl","binary_version":"0.17-2build6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116130.json"}}],"schema_version":"1.9.2","severity":[{"type":"Ubuntu","score":"medium"}]}
