{"id":"DEBIAN-CVE-2026-42946","details":"A vulnerability exists in the ngx_http_scgi_module and ngx_http_uwsgi_module modules that may result in excessive memory allocation or an over-read of data. When scgi_pass or uwsgi_pass is configured, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to read the memory of the NGINX worker process or restart it.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","modified":"2026-09-01T16:06:43.260758505Z","published":"2026-05-13T16:16:50.340Z","upstream":["CVE-2026-42946"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42946"}],"affected":[{"package":{"name":"nginx","ecosystem":"Debian:12","purl":"pkg:deb/debian/nginx?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.22.1-9+deb12u8"}]}],"versions":["1.22.1-9","1.22.1-9+deb12u1","1.22.1-9+deb12u2","1.22.1-9+deb12u3","1.22.1-9+deb12u4","1.22.1-9+deb12u5","1.22.1-9+deb12u6","1.22.1-9+deb12u7"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42946.json"}},{"package":{"name":"nginx","ecosystem":"Debian:13","purl":"pkg:deb/debian/nginx?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.3-3+deb13u6"}]}],"versions":["1.26.3-3","1.26.3-3+deb13u1","1.26.3-3+deb13u2","1.26.3-3+deb13u3","1.26.3-3+deb13u4","1.26.3-3+deb13u5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42946.json"}},{"package":{"name":"nginx","ecosystem":"Debian:14","purl":"pkg:deb/debian/nginx?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.30.0-4"}]}],"versions":["1.26.3-3","1.28.0-1","1.28.0-2","1.28.0-3","1.28.0-4","1.28.0-5","1.28.0-6","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.2-3","1.28.2-4","1.28.3-1","1.28.3-2","1.30.0-1","1.30.0-2","1.30.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42946.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
