crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption
A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...
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...
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...
net-imap: ruby: Net::IMAP: Information disclosure via man-in-the-middle attack bypassing TLS
A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAPstarttls method, the library improperly handles certain responses received during STARTTLS negotiation. A man-in-the-middle MITM attacker can inject a predicted tagged OK response...

SUSE CVE-2026-55952
The Erlang/OTP ssl application does not validate that the PSK identity list and binder list carried in a TLS 1.3 ClientHello pre-shared key extension have equal length before passing them to the session ticket handler. In tlshandshake13:handlepresharedkey/3, an OfferedPreSharedKeys record with a...
ALPINE-CVE-2026-8286
A vulnerability exists where a new transfer that uses STARTTLS to upgrade the connection might reuse an existing live connection even though the TLS configuration mismatches so it should not...
CVE-2026-54891
A flaw was found in Erlang's SSL Secure Sockets Layer component. A network-positioned attacker can exploit this vulnerability by injecting unauthenticated plaintext data into a client's TLS Transport Layer Security handshake. The client application may then process this injected data as if it wer...
