CVE-2026-46428

A flaw was found in lettre, a mailer library for Rust. An inverted-boolean bug in the boring-tls integration silently disables TLS hostname verification for users employing the default strict configuration. A remote on-path attacker can exploit this by presenting any valid TLS certificate, allowi...

erlang/otp: Erlang/OTP ssl client: Authentication bypass via unoffered anonymous cipher suite acceptance

A flaw was found in the Erlang/OTP ssl client. This vulnerability allows an on-path attacker to bypass server authentication in TLS 1.2 and earlier and DTLS connections. By tricking the client into accepting an unoffered anonymous cipher suite, the attacker can complete the handshake without a...

CVE-2026-55953

The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tlshandshake:hello/5 handler validates the negotiated protocol version and the downgrade...

EEF-CVE-2026-55953 TLS 1.2 and DTLS client accepts unoffered anonymous cipher suite, bypassing server authentication

Summary The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tls\handshake:hello/5 handler validates the negotiated protocol version and the...

CVE-2026-55953

Summary: CVE-2026-55953 affects Erlang/OTP SSL/TLS client when using TLS 1.2 and DTLS. The client fails to verify that the server-chosen cipher suite in ServerHello was among the suites offered in ClientHello. An on-path attacker can respond with a ServerHello using an anonymous cipher suite (e.g...

GHSA-G7HG-VRCF-MVMR Netty: Out-of-date OCSP Responses Accepted by OcspServerCertificateValidator

Summary OcspServerCertificateValidator flags an out-of-date OCSP response but does not stop processing it, so an expired GOOD response is still reported as VALID, letting an on-path attacker replay a stale GOOD response to bypass revocation of a since-revoked certificate. Details In...

CVE-2026-46428 lettre has TLS hostname verification disabled when using Boring TLS backend

lettre is a a mailer library for Rust. Starting in version 0.10.1 and prior to version 0.11.22, an inverted-boolean bug in lettre's boring-tls integration silently disables TLS hostname verification for callers using the default strict configuration. An on-path attacker presenting any chain-valid...

CVE-2026-44434

Quicly (QUIC protocol implementation used with H2O HTTP server) was vulnerable to stateless reset injection before commit dccf5d4 due to lack of packet entry validation, allowing an on-path attacker to reset QUIC connections by exploiting zero-initialized secret-pattern slots. The issue has been ...

CVE-2026-44434 Quicly is vulnerable to stateless reset injection

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit dccf5d4, Quicly was vulnerable to stateless reset injection through lack of packet entry validation. The QUIC protocol is designed to withstand packet injection attacks, once the...

CVE-2026-15925

Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this b...

Name of the Vulnerable Software and Affected Versions Quicly versions prior to commit dccf5d4 Description Quicly, an IETF QUIC protocol implementation used in the H2O HTTP server, is susceptible to stateless reset injection. The issue stems from a lack of packet entry validation when handling...

PT-2026-53090

Name of the Vulnerable Software and Affected Versions Nmap versions 7.0.0 through 7.99 Description An issue exists in the ipv6 get data primitive function libnetutil/netutil.cc where the IPv6 extension-header walk is not kept within the captured packet. This causes the pointer to advance past the...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to exposure of QUIC stateless reset tokens through connection ID generation, which allows an on-path attacker to derive the token and send spoofed Stateless Reset packets to terminate active connections...

Netty: QUIC stateless reset token material exposed through header-visible connection IDs

Summary Netty QUIC exposes the stateless reset token on the network path when using the default HMAC-based connection-ID and stateless-reset-token generators. The reset token for the server's current source connection ID can be derived from bytes that appear as the connection ID in QUIC headers...
