{"id":"DEBIAN-CVE-2026-48142","details":"NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When content is served or proxied through a location block with both source_charset utf-8; and a charset directive (for example, charset koi8-r;) configured, remote, unauthenticated attackers can send requests (in conjunction with conditions beyond their control) to cause a heap buffer over-read in the NGINX worker process, leading to limited disclosure of memory or a restart.    Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","modified":"2026-09-01T16:06:47.534188408Z","published":"2026-06-17T15:16:59.040Z","upstream":["CVE-2026-48142"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-48142"}],"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+deb12u9"}]}],"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","1.22.1-9+deb12u8"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48142.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+deb13u7"}]}],"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","1.26.3-3+deb13u6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48142.json"}},{"package":{"name":"nginx","ecosystem":"Debian:14","purl":"pkg:deb/debian/nginx?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.30.1-5"}]}],"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","1.30.0-4","1.30.1-1","1.30.1-2","1.30.1-3","1.30.1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48142.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
