{"id":"DEBIAN-CVE-2026-120635","details":"CGI versions before 5.00 for Perl allow form fields to be smuggled past proxies and WAFs via multipart parsing that differs from the RFCs.  The multipart/form-data parser matches the boundary anywhere rather than at the start of a line, uses the boundary without its leading -- for some client-supplied User-Agent values, finds the Content-Disposition name and filename inside the quoted values of other parameters, and corrupts parts when the boundary nears the 4096-byte read size.","modified":"2026-11-04T08:00:09.843010889Z","published":"2026-11-04T00:17:24.730Z","upstream":["CVE-2026-120635"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-120635"}],"affected":[{"package":{"name":"libcgi-pm-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libcgi-pm-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.55-1","4.57-1","4.59-1","4.60-1","4.61-1","4.62-1","4.63-1","4.64-1","4.65-1","4.66-1","4.67-1","4.68-1","4.70-1","4.71-1","4.72-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120635.json"}},{"package":{"name":"libcgi-pm-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libcgi-pm-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.68-1","4.70-1","4.71-1","4.72-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120635.json"}},{"package":{"name":"libcgi-pm-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libcgi-pm-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.68-1","4.70-1","4.71-1","4.72-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120635.json"}}],"schema_version":"1.9.2"}
