rclone versions before v1.75.0 fail to reject transport downgrades in redirect handling, allowing Basic authorization and Cookie headers to be replayed over plaintext HTTP after same-host HTTPS-to-HTTP redirects. An on-path attacker observing the plaintext hop can capture and reuse credentials to...

CVE-2026-66732

Sonic 3 A.I.R. before commit 2492d18 contains a missing source address validation vulnerability in ConnectionManager where established connections are resolved by a two-byte local connection handle alone without verifying that the datagram source address matches the registered remote address for...

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or...

CVE-2026-60007

In Eclipse Milo versions 0.6.0 through 1.1.4, username-token processing returns distinguishable errors for invalid RSA PKCS1 v1.5 padding and other authentication failures, allowing an on-path attacker who captures a victim's Basic128Rsa15-encrypted username token to use repeated unauthenticated...

CVE-2026-60007

CVE-2026-60007 affects Eclipse Milo versions 0.6.0 through 1.1.4, where username-token processing reveals distinguishable errors for invalid RSA PKCS#1 v1.5 padding and other authentication failures. This enables a network-accessible, on-path attacker who captures a victim’s Basic128Rsa15-encrypt...

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...
