golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

golang.org/x/net/html: golang.org/x/net/html: Arbitrary code execution via Cross-Site Scripting

A flaw was found in golang.org/x/net/html. A remote attacker could exploit this vulnerability by providing specially crafted HTML. When this arbitrary HTML is parsed and rendered, it can result in an unexpected HTML tree, bypassing input sanitization. This can be leveraged to execute Cross-Site...

golang.org/x/net/html: golang: golang.org/x/net/html: Cross-Site Scripting via HTML parsing bypass

A flaw was found in golang.org/x/net/html. When arbitrary HTML is parsed and then rendered, it can result in an unexpected HTML tree. This allows an attacker to bypass HTML sanitization mechanisms, leading to Cross-Site Scripting XSS attacks in applications. Such attacks can result in information...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
