encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

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...

html/template: golang: Go html/template: Cross-Site Scripting via pathological input

A flaw was found in the html/template component of Go golang. Pathological inputs could prematurely close an unescaped forward slash '/', allowing an attacker to inject arbitrary content. This could lead to Cross-Site Scripting XSS, where malicious scripts are executed in a user's browser,...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-72816

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - go-chi/chi through 5.2.1 contains an IP spoofing vulnerability in the RealIP middleware middleware/realip.go. The realIP function reads client-controlled header...

CVE-2026-72817: Insufficient Verification of Data Authenticity

go-chi/chi versions 0.9.0 before 5.3.0 contains an IP spoofing vulnerability in the RealIP middleware, which resolves the request source IP Request.RemoteAddr using the first IP in the X-Forwarded-For header without validating trusted proxies. A malicious client can prepend a forged IP as the fir...

CVE-2026-72816: Authentication Bypass by Spoofing

go-chi/chi through 5.2.1 contains an IP spoofing vulnerability in the RealIP middleware middleware/realip.go. The realIP function reads client-controlled headers True-Client-IP, X-Real-IP, and X-Forwarded-For and overwrites r.RemoteAddr without verifying that the request originated from a trusted...

Linux Distros Unpatched Vulnerability : CVE-2026-56865

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist...

Linux Distros Unpatched Vulnerability : CVE-2026-56864

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A malicious GOSUMDB was capable of serving arbitrary module content not contained within the transparency log. This attack allows for a coordinating GOPROXY and...

Linux Distros Unpatched Vulnerability : CVE-2026-72817

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - go-chi/chi versions 0.9.0 before 5.3.0 contains an IP spoofing vulnerability in the RealIP middleware, which resolves the request source IP Request.RemoteAddr...

CVE-2026-72815: Authentication Bypass by Spoofing

go-chi chi versions = 5.2.1 and before 5.3.0 contain an IP spoofing vulnerability in the RealIP middleware, which blindly trusts the first leftmost value of the X-Forwarded-For HTTP header. A remote attacker can bypass IP-based access control lists and rate-limiting mechanisms, and forge log...

Golang 1.25.x < 1.25.13 / 1.26.x < 1.26.6 Multiple Vulnerabilities

The version of Golang running on the remote host is 1.25.x prior to 1.25.13, or 1.26.x prior to 1.26.6. It is, therefore, affected by multiple vulnerabilities in the standard library and the toolchain, as referenced in the golang-announce advisory. - The ToASCII and ToUnicode functions incorrectl...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...
