crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

New API: SSRF Protection Bypass via Unresolved Hostname in Notification URLs

Summary The default SSRF protection configuration did not apply IP filtering to hostnames. With ApplyIPFilterForDomain disabled by default, URL validation checked domain allow/block rules but did not resolve a hostname and validate the resolved IP address. Authenticated users could configure...

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...

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...

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...
