net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

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...

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...

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...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

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...

net/mail: golang: net/mail: Denial of Service via pathological email address parsing

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...

CVE-2026-84382

HTTPX2 is a next generation HTTP client for Python. Prior to 2.12.0, the HTTPX2 content decoders in src/httpx2/httpx2/decoders.py fully inflate each gzip, deflate, br, or zstd network chunk before iterbytes or aiterbytes yields bounded pieces to the application. A 64 KiB compressed chunk can expa...

GO-2026-6355 Prevent DoS on deadlocked established channel in golang.org/x/crypto/ssh

Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and tear the connectio...

GO-2026-6354 Prevent DoS on deadlocked undecided channel in golang.org/x/crypto/ssh

Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time,...

CVE-2026-84378

A flaw was found in httpx2, a Python HTTP client. The Server-Sent Events SSE parser in httpx2 can be exploited by a remote attacker. By sending a specially crafted stream where an unterminated line is split across many response chunks, the parser repeatedly copies and rescans buffered text. This...

CVE-2026-84382

A flaw was found in httpx2, a Python HTTP client. The content decoders in httpx2 fully inflate compressed network chunks such as gzip, deflate, br, or zstd before yielding bounded pieces to the application. This can lead to a small compressed chunk expanding significantly in memory, for example, ...

js-yaml: js-yaml: Denial of Service vulnerability in YAML parsing

A flaw was found in js-yaml, a JavaScript YAML parser. An attacker can exploit this by providing a specially crafted YAML document that causes the parser to perform excessive processing when handling merge keys with empty sources. This can lead to prolonged CPU consumption, effectively causing a...

CVE-2026-84378

HTTPX2 is a next generation HTTP client for Python. From 2.5.0 until 2.10.0, the HTTPX2 Server-Sent Events parser in src/httpx2/httpx2/sse.py repeatedly copies and rescans buffered text in SSELineDecoder.decode when an attacker-controlled or compromised SSE endpoint splits one unterminated line...

CVE-2026-77121

A user account with permission to deploy artifacts to a hosted Maven repository could upload a POM file containing an oversized metadata field. This causes future attempts to list or browse that repository's components to permanently fail until an administrator repairs the underlying data. Only t...
