undici: undici: TLS certificate validation bypass in BalancedPool via dropped connect options

A flaw was found in undici's BalancedPool component. This vulnerability allows a remote attacker to bypass Transport Layer Security TLS certificate validation. The BalancedPool constructor incorrectly processes its options, silently discarding custom certificate validation functions. Consequently...

CVE-2026-73251

A flaw was found in Mongoose. When configured with a Certificate Authority CA bundle, the built-in Transport Layer Security TLS implementation matches server certificates by name without verifying their cryptographic signatures. A remote network attacker can exploit this vulnerability by presenti...

CVE-2026-102759

NetX Secure TLS accepts an empty application-data record without verifying its message authentication code. In nxsecureverifymac, a decrypted application record whose length equals the negotiated MAC size is treated as valid and returns success after advancing the receive sequence number. The...

CVE-2026-102758

The nxsecurex509asn1tlvblockparse function parses ASN.1 TLV tag-length-value blocks out of DER-encoded data. It is the primitive underneath all X.509 certificate parsing in NetX Secure, and therefore runs on certificates supplied by a remote peer during the TLS handshake. The function reads the...

CVE-2026-102728

Two client-side TLS/DTLS handshake parsers in NetX Secure read fields from a server-supplied message before validating that the message is long enough to contain them. Both are bounded out-of-bounds reads on a remotely reachable path, both are reached from a TLS or DTLS client connecting to a...

CVE-2026-102728

The NetX Secure software contains two out-of-bounds reads within its client-side TLS/DTLS handshake parsers . The vulnerability occurs because the parsers read fields from a server-supplied message before validating that the message is sufficiently long. Although bounds checks are present and fun...
