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: 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...

XAPI: Missing TLS verification in some SDKs

ISSUE DESCRIPTION XAPI provides SDKs; bindings for the API in various programming languages. These are artefacts from a build of XAPI, intended for integration into 3rd party products. In all SDKs, there is a main RPC connection to the XAPI host. TLS for this connection is verified properly, or...

PT-2026-64461

In wolfSSL before 5.5.2, if callback functions are enabled via the WOLFSSL CALLBACKS flag, then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. WOLFSSL CALLBACKS is only intended for debugging...

PT-2026-64457

In wolfSSL before 5.2.0, a TLS 1.3 server cannot properly enforce a requirement for mutual authentication. A client can simply omit the certificate verify message from the handshake, and never present a certificate...

PT-2026-64456

In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sig algo field differs between the certificate verify message and the certificate message...

PT-2026-64459

An issue was discovered in wolfSSL before 5.5.0. When a TLS 1.3 client connects to a wolfSSL server and SSL clear is called on its session, the server crashes with a segmentation fault. This occurs in the second session, which is created through TLS session resumption and reuses the initial struc...

PT-2026-64469

Heap-based buffer overflow in the KCAPI ECC code path of wc ecc import x963 ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkey raw buffer via a crafted oversized EC public key point. The WOLFSSL KCAPI ECC code path copies the input to...

PT-2026-64460

In wolfSSL before 5.5.1, malicious clients can cause a buffer overflow during a TLS 1.3 handshake. This occurs when an attacker supposedly resumes a previous TLS session. During the resumption Client Hello a Hello Retry Request must be triggered. Both Client Hellos are required to contain a list ...

PT-2026-64465

Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...

PT-2026-64463

In wolfSSL 5.8.2 and earlier, a logic flaw existed in the TLS 1.2 server state machine implementation. The server could incorrectly accept the CertificateVerify message before the ClientKeyExchange message had been received. This issue affects wolfSSL before 5.8.4 wolfSSL 5.8.2 and earlier is...

On the Security Implications of PQC in TLS: Handshake Exhaustion and IDS Degradation

Post-Quantum Cryptography PQC is increasingly being integrated into TLS 1.3 to enhance resilience against quantum-enabled attacks. However, the additional computational and communication overhead introduced by PQC primitives during the handshake phase may also amplify the impact of TLS handshake...
