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.

CWE-776 - Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')

Threats
Impact Important

A flaw was found in the `net/http/httputil` package, specifically within the `ReverseProxy` component. This vulnerability allows the `ReverseProxy` to forward query parameters that are not visible to `Rewrite` functions. This occurs because the `ReverseProxy` does not correctly consider the `url.ParseQuery` limit on the total number of query parameters. A remote attacker could exploit this to send hidden query parameters, potentially bypassing security policies or controls implemented by `Rewrite` functions, leading to information disclosure or unexpected behavior.

Threats
Impact Moderate

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.

CWE-770 - Allocation of Resources Without Limits or Throttling
Affected products
Fixed 16 products, the same list as for CVE-2026-33818
Known not affected 9 products, the same list as for CVE-2026-33818
Threats
Impact Important

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.

CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Affected products
Fixed 16 products, the same list as for CVE-2026-33818
Known not affected 9 products, the same list as for CVE-2026-33818
Threats
Impact Important

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.

CWE-776 - Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
Affected products
Fixed 16 products, the same list as for CVE-2026-33818
Known not affected 9 products, the same list as for CVE-2026-33818
Threats
Impact Important

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.

CWE-770 - Allocation of Resources Without Limits or Throttling
Affected products
Fixed 16 products, the same list as for CVE-2026-33818
Known not affected 9 products, the same list as for CVE-2026-33818
Threats
Impact Important

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.

CWE-1050 - Excessive Platform Resource Consumption within a Loop
