A flaw was found in the morgan HTTP request logging middleware. The :remote-user token writes the Basic auth username to access logs without neutralizing CR/LF control characters. An unauthenticated remote attacker can inject forged log lines via a crafted Authorization header, breaking one-request-per-line log structure and enabling log forgery against downstream consumers.

Threats
Impact
Moderate
A flaw was found in undici. An attacker-controlled upstream server can exploit a vulnerability in Undici's HTTP/1.1 client, specifically related to response queue poisoning on reused keep-alive sockets. This allows the attacker to inject an unsolicited HTTP/1.1 response onto an idle socket. Consequently, when the client dispatches a new request on that socket, it may associate the injected response with the new request, leading to responses being delivered to unintended recipients or requests. This could result in a low impact on data integrity.

Threats
Impact
Low
A flaw was found in undici. When using Socks5ProxyAgent, undici incorrectly reuses a single connection pool across different origins. This can lead to cross-origin request routing, where sensitive credentials and data intended for one destination are sent to another. Consequently, responses from unintended origins may be trusted, and secure HTTPS connections could be silently downgraded to unencrypted HTTP, resulting in information disclosure and data integrity issues.

Threats
Impact
Important
A flaw was found in Undici. The cache interceptor in shared-cache mode incorrectly classifies certain responses as cacheable due to improper handling of whitespace-padded Cache-Control header field names. This vulnerability allows an unauthenticated attacker to access authenticated user data from the cache, leading to information disclosure. This occurs when both authenticated and unauthenticated requests resolve to the same cache key.

Threats
Impact
Moderate
A flaw was found in undici. The cookie parser in the `parseSetCookie` function incorrectly decodes cookie values, which is contrary to standard specifications. This vulnerability allows an attacker-controlled upstream to inject arbitrary HTTP response headers, such as `Set-Cookie`, `Location`, or `Cache-Control`. The primary consequence is HTTP response header injection, which can lead to session fixation, open redirect, or cache poisoning.

Threats
Impact
Moderate
A flaw was found in undici. When undici's ProxyAgent is configured with a SOCKS5 proxy Uniform Resource Identifier (URI), it silently ignores Transport Layer Security (TLS) options, such as custom Certificate Authorities (CAs). This allows a remote attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and tampering with HTTPS communications. The connection falls back to Node.js's default trust store, bypassing intended security configurations and potentially leading to information disclosure or arbitrary code execution.

Important
A flaw was found in undici. When undici processes Set-Cookie headers, it incorrectly interprets the SameSite attribute, accepting partial matches instead of exact ones. This allows a malicious server to downgrade a cookie's SameSite policy to a less secure setting, potentially leading to unintended information disclosure or a weakening of security protections for the user.

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion, resulting in a denial of service (DoS) for affected applications using the undici WebSocket client or WebSocketStream API.

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker can exploit this vulnerability by providing a specially crafted YAML document that repeatedly uses the same alias in a merge sequence. This can lead to algorithmic CPU exhaustion, causing the Node.js worker or event loop to be blocked for an extended period, resulting in a denial of service (DoS) for the affected system.
