CVE-2026-19201

An uncontrolled recursion vulnerability in the Windows SIPA event log parser of Google go-attestation versions up to and including 0.6.1 allows an attacker to cause a denial of service DoS. The WinEvents.readELAMAggregation function recurses for every nested elamAggregation sub-event without...

CVE-2026-19201 Denial of Service via Unbounded Recursion in go-attestation Windows SIPA Parser

An uncontrolled recursion vulnerability in the Windows SIPA event log parser of Google go-attestation versions up to and including 0.6.1 allows an attacker to cause a denial of service DoS. The WinEvents.readELAMAggregation function recurses for every nested elamAggregation sub-event without...

Summary opentelemetry-go is used by IBM Fusion Data Foundation, which could cause a Denial of Service. CVE-2026-29181. Vulnerability Details CVEID:CVE-2026-29181 DESCRIPTION: OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction...

CVE-2026-76905

A flaw was found in kin-openapi, a Go project for handling OpenAPI files. An unauthenticated client can exploit this vulnerability by sending a malformed non-string scalar field in a multipart/form-data request body. This can cause applications that render validation errors through specific...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception through the HTTP/2 header processing path in internal/transport/http2server.go and internal/xds/server/routing.go. An attacker can crash the server by sending a gRPC request that omits both the :authority and Host...

gRPC-Go xDS servers: Denial of Service (DoS) via crash due to missing `:authority` and `Host` headers

A vulnerability exists in gRPC-Go servers configured with xds.NewGRPCServer where a crafted request missing both :authority and Host headers can cause a server panic, resulting in a Denial of Service DoS. Servers built with xds.NewGRPCServer install an xDS routing interceptor on every RPC. This...

GHSA-2V4P-QF9Q-27WJ gRPC-Go xDS servers: Denial of Service (DoS) via crash due to missing `:authority` and `Host` headers

A vulnerability exists in gRPC-Go servers configured with xds.NewGRPCServer where a crafted request missing both :authority and Host headers can cause a server panic, resulting in a Denial of Service DoS. Servers built with xds.NewGRPCServer install an xDS routing interceptor on every RPC. This...

GHSA-QC2Q-P7WX-3PX3 gRPC-Go: xDS RBAC HTTP Filter bypass via mixed-case Header Matching and gRFC A41 validation evasion

Summary A vulnerability in the xDS RBAC HTTP filter implementation in grpc-go allows remote attackers to bypass authorization policies specifically DENY rules by using mixed-case or canonical-case header matchers e.g., X-Role instead of x-role. Additionally, the safety guards introduced by gRFC A...

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...

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...

net/mail: golang: Go net/mail: Denial of Service via crafted email inputs

A flaw was found in the net/mail package of the Go programming language. An attacker could provide specially crafted inputs to the ParseAddress, ParseAddressList, or ParseDate functions. This could lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service DoS for...

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/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...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

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,...
