CVE-2026-40198

CVE-2026-40198/40199 affect Net::CIDR::Lite for Perl prior to 0.23. The IPv6 handling flaw in _pack_ipv6() allows malformed uncompressed IPv6 addresses and IPv4-mapped IPv6 addresses to produce packed values of incorrect length, causing mask and comparison operations to misbehave. Consequently, f...

golang: net/url: Memory exhaustion in query parameter parsing in net/url

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted...

net/mail: Excessive CPU consumption in ParseAddress in net/mail

A denial of service vulnerability has been discovered in the golang net/mail module. The ParseAddress function constructed domain-literal address components through repeated string concatenation which when parsing large domain-literal components, could cause excessive CPU consumption...

net/textproto: Excessive CPU consumption in Reader.ReadResponse in net/textproto

The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a response is large, this can cause excessive CPU consumption...

net/http: CrossOriginProtection bypass in net/http

A CrossOriginProtection bypass has been discovered in the golang net/http package. When using http.CrossOriginProtection, the AddInsecureBypassPattern method can unexpectedly bypass more requests than intended. CrossOriginProtection then skips validation, but forwards the original request path,...
