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.

Threats
Impact
Important
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.

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.
8.1 (High)
Affected products
Fixed
12 products, the same list as for
CVE-2026-33818
Known not affected
39 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.
7.5 (High)
Affected products
Fixed
12 products, the same list as for
CVE-2026-33818
Known not affected
39 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.
7.5 (High)
Affected products

12 products, the same list as for
CVE-2026-33818
Known not affected
39 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.

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.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
