CVE-2026-27137

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly applied, and only the last constraint will be considered.

Threats
Impact Important
CVE-2026-33376

A flaw in Grafana's Auth Proxy IPv6 allow-list incorrectly defaults to a broad /32 subnet mask instead of a strict /128. This misconfiguration allows remote attackers to bypass access restrictions, potentially leading to unauthorized access and data manipulation.

7.4 (High)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N
CWE-183 - Permissive List of Allowed Inputs
Affected products
Fixed 13 products, the same list as for CVE-2026-27137
Threats
Impact Moderate
CVE-2026-33377

A flaw was found in Grafana. A user with editor privileges can overwrite a dashboard not owned by them, leading to privilege escalation on that specific dashboard. This allows the editor to gain administrative control over the affected dashboard.

7.1 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N
CWE-267 - Privilege Defined With Unsafe Actions
Affected products
Fixed 13 products, the same list as for CVE-2026-27137
Threats
Impact Moderate
CVE-2026-33810

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 attacker to bypass certificate validation, potentially leading to the acceptance of a malicious certificate that should have been rejected. This issue specifically impacts the validation of trusted certificate chains.

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:L

Affected products

Threats
Impact Important
CVE-2026-33818

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) condition.

Impact Important
CVE-2026-39820

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 applications processing these inputs.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Threats
Impact Important
CVE-2026-39821

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 access to a restricted hostname the ASCII check would have rejected.

8.2 (High)

Threats
Impact Important
CVE-2026-42499

A flaw was found in the `net/mail` package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the `consumePhrase` function, it can lead to excessive resource consumption due to quadratic string concatenation, resulting in a Denial of Service (DoS) condition.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Impact Important
CVE-2026-42504

A flaw was found in the Golang MIME (Multipurpose Internet Mail Extensions) package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service (DoS) for the affected system.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Threats
Impact Important
CVE-2026-56853

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 oversight could allow a remote attacker to maintain open connections indefinitely, potentially leading to a Denial of Service (DoS) by exhausting server resources.

7.5 (High)

Impact Important
CVE-2026-56858

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, potentially compromising user data or actions.

8.1 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N

Impact Important
CVE-2026-56859

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 the affected application.

7.5 (High)

Impact Important
CVE-2026-56860

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 allocation. This can result in a Denial of Service (DoS) due to resource exhaustion.

7.5 (High)

CVE-2026-56862

A flaw was found in the `crypto/tls` package, part of `golang`. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service (DoS) condition.
