{"id":"DEBIAN-CVE-2026-78222","details":"A vulnerability exists in NGINX JavaScript where a malformed HTTP response received by ngx.fetch() can crash an NGINX worker when trusted JavaScript reads Response.statusText. Exploitation requires control or influence over the fetched HTTP response.  Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system. There is no control plane exposure; this is a data plane issue only.     Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","modified":"2026-09-14T17:03:34.068297242Z","published":"2026-09-02T16:17:23.557Z","upstream":["CVE-2026-78222"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-78222"}],"affected":[{"package":{"name":"libnginx-mod-js","ecosystem":"Debian:12","purl":"pkg:deb/debian/libnginx-mod-js?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.12-1","0.7.12-2","0.7.12-2~exp1","0.7.12-2~exp2","0.7.9-2","0.8.0-1","0.8.1-1","0.8.2-1","0.8.4-1","0.8.5-1","0.8.9-1","0.9.1-1","0.9.4-1","0.9.6-1","0.9.8-1","0.9.9-1","0.9.9-2","1.0.0-1","1.0.0-2","1.0.0-3","1.0.0-4","1.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-78222.json"}},{"package":{"name":"libnginx-mod-js","ecosystem":"Debian:13","purl":"pkg:deb/debian/libnginx-mod-js?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.8.9-1","0.9.1-1","0.9.4-1","0.9.6-1","0.9.8-1","0.9.9-1","0.9.9-2","1.0.0-1","1.0.0-2","1.0.0-3","1.0.0-4","1.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-78222.json"}},{"package":{"name":"libnginx-mod-js","ecosystem":"Debian:14","purl":"pkg:deb/debian/libnginx-mod-js?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1-1"}]}],"versions":["0.8.9-1","0.9.1-1","0.9.4-1","0.9.6-1","0.9.8-1","0.9.9-1","0.9.9-2","1.0.0-1","1.0.0-2","1.0.0-3","1.0.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-78222.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/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"}]}
