nodejs: Node.js: Denial of Service via DNS responses with excessive A records

A denial of service DoS vulnerability in Node.js allows a remote attacker to crash the application. By sending a specially crafted DNS response with an excessive number of 'A' records, an attacker can cause the dns.resolveAny function to unexpectedly abort the process...

nodejs: Information disclosure due to improper permission enforcement

A flaw was found in Node.js. The permission model enforcement, specifically related to process.report functionality, allows an attacker to write or overwrite files in locations outside of the intended secure paths. This vulnerability can lead to the disclosure of sensitive information or bypass t...

nodejs: Node.js: Permission Model flaw allows trace logs to bypass filesystem write restrictions

A flaw in the Node.js Permission Model allows traceevents.createTracing.enable to bypass --allow-fs-write restrictions and write trace logs outside intended paths, potentially leading to unauthorized information disclosure...

nodejs: Node.js: mTLS client identities can be reused due to HTTPS Agent connection flaw

A flaw was found in Node.js. The HTTPS Agent, responsible for managing secure connections, can incorrectly reuse client identities across different requests. This occurs due to a technical issue with PFX object-array key collisions during connection reuse. As a result, a client's identity,...

nodejs: Node.js: Denial of Service vulnerability

A flaw was found in Node.js. A malicious actor could exploit this vulnerability by providing a specially crafted input to the synchronous node:zlib APIs. This could cause the Node.js process to crash, leading to a denial of service and making the application unavailable to users...

nodejs: Node.js: Remote memory exhaustion via HTTP/2 retained header blocks

A flaw was found in Node.js's handling of HTTP/2. This vulnerability allows a remote attacker to bypass maxSessionMemory limits by sending specially crafted HTTP/2 retained header blocks. This can lead to memory exhaustion, resulting in a denial of service DoS for the affected system...

nodejs: Node.js: Request smuggling via HTTP client header truncation

A flaw was found in Node.js. The Node.js HTTP client can cause a request desynchronization in forwarding proxies, potentially leading to request smuggling. This vulnerability arises when the HTTP client omits certain headers, such as Content-Length, from being visible to the proxy application whi...

nodejs: HTTPS Agent TLS session reuse skips hostname verification

A flaw was found in Node.js. An incomplete fix for a previous vulnerability allows the HTTPS Agent to reuse Transport Layer Security TLS sessions, bypassing hostname verification across different identity policies. This could enable an attacker to impersonate a legitimate server, leading to...
