{"id":"DEBIAN-CVE-2026-8450","details":"HTTP::Daemon versions before 6.17 for Perl allow OS command injection via send_file().  send_file() opens its string argument with Perl's 2-arg open(). The 2-arg form interprets magic prefixes: '| cmd' and 'cmd |' open a pipe to a subprocess, '\u003e path' and '\u003e\u003e path' open the path for write or append.  Untrusted input passed to send_file() can run OS commands at the daemon process UID. The read-pipe form ('cmd |') also leaks subprocess stdout into the HTTP response body. The write-mode forms can create or truncate files at attacker chosen paths.","modified":"2026-09-01T16:07:07.062680467Z","published":"2026-05-27T05:16:23.067Z","upstream":["CVE-2026-8450"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-8450"}],"affected":[{"package":{"name":"libhttp-daemon-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libhttp-daemon-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.16-1+deb13u1~deb12u1"}]}],"versions":["6.16-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8450.json"}},{"package":{"name":"libhttp-daemon-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libhttp-daemon-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.16-1+deb13u1"}]}],"versions":["6.16-1","6.16-1+deb13u1~deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8450.json"}},{"package":{"name":"libhttp-daemon-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libhttp-daemon-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.17-1"}]}],"versions":["6.16-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8450.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
