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...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-72815

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 = 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...

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...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

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...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

google.golang.org/grpc/grpc-go: google.golang.org/grpc/authz: gRPC-Go: Authorization bypass due to improper HTTP/2 path validation

A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 :path pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed :path that omits the mandato...

DEBIAN-CVE-2026-56853

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this...
