Details
It was discovered that nginx incorrectly handled large headers when
proxying HTTP/2 traffic. A remote attacker could use this issue to cause
nginx to crash, resulting in a denial of service, or possibly execute
arbitrary code. The default compiler options for affected releases should
reduce the vulnerability to a denial of service. (CVE-2026-42055)
It was discovered that nginx incorrectly handled character set conversion
under certain circumstances. A remote attacker could possibly use this
issue to obtain sensitive information or cause nginx to crash, resulting in
a denial of service. (CVE-2026-48142)
