GHSA-6VJ9-MWQ6-2F5V Nodemailer: Process-global DNS cache reuses TLS `servername` across transports, enabling cross-tenant SMTP credential disclosure
Summary Nodemailer's process-global DNS cache is keyed only by host, but each cache entry also stores the caller-specific TLS servername. When two direct SMTPS transports use the same DNS host with different tls.servername values, the first transport's server name is returned to the second...
Improper Certificate Validation
Overview @grpc/grpc-js is a gRPC Library for Node Affected versions of this package are vulnerable to Improper Certificate Validation via getAuthContext in server-interceptors.ts and the TLS session handling in transport.ts, where the authorized property of a TLS socket is not checked before...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages
A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...
crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building
A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

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 ...
crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages
A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

CVE-2026-93824
A flaw was found in the Linux kernel's Transport Layer Security TLS subsystem. A local user can trigger this vulnerability by configuring TLS keys on a network socket already attached to a Berkeley Packet Filter BPF socket map sockmap. This unsupported integration exposes latent flaws in the...
curl: libcurl: Improper certificate validation due to cached TLS settings reuse
A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...
curl: curl: Insecure connection establishment due to TLS configuration mismatch
A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
