GHSA-6HG6-V5C8-FPHQ Apache Log4j Core: `verifyHostName` attribute silently ignored in TLS configuration

The fix for CVE-2025-68161 was incomplete: it addressed hostname verification only when enabled via the log4j2.sslVerifyHostName system property, but not when configured through the verifyHostName attribute of the element. Although the verifyHostName configuration attribute was introduced in Log4...

nodejs: Nodejs memory leak

A resource consumption flaw has been discovered in NodeJS. A memory leak in Node.js’s OpenSSL integration occurs when converting X.509 certificate fields to UTF-8 without freeing the allocated buffer. When applications call socket.getPeerCertificatetrue, each certificate field leaks memory,...

nodejs: Nodejs denial of service

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch

A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS Transport Layer Security hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security...

nodejs: Node.js: Certification validation bypass in TLS host verification

A flaw was found in Node.js. An attacker can exploit a vulnerability in the Transport Layer Security TLS host verification process to bypass certification validation. This bypass could allow an attacker to intercept or alter communications, potentially leading to information disclosure or integri...

Node.js: Node.js: Trust-policy bypass due to hostname matching inconsistency

A flaw was found in Node.js. An inconsistency in how Node.js matches hostnames can be exploited by a remote attacker in multi-context mTLS mutual Transport Layer Security setups. This vulnerability allows for a trust-policy bypass, potentially leading to unauthorized access to sensitive informati...

nodejs: Node.js: Silent authority rebinding due to embedded-nul hostnames in TLS handling

A flaw was found in Node.js. This vulnerability in the TLS Transport Layer Security hostname handling allows embedded null characters in hostnames. This can lead to silent authority rebinding, potentially enabling an attacker to redirect network traffic to an unintended server and disclose...
