rustls-webpki through 0.103.12 and 0.104.0-alpha releases before 0.104.0-alpha.7 contains a reachable panic in bit string flags in src/der.rs. The input guard fails to reject a named-bit BIT STRING whose content is exactly 0x00 zero padding bits and no data bytes, so raw bits.len - 1 underflows o...

rustls-webpki the Rust webpki fork used by rustls versions = 0.101.0 and prior to 0.103.12 and 0.104.0-alpha.6 incorrectly accepted permitted-subtree DNS name constraints for certificates asserting a wildcard name. For example, a name constraint of accept.example.com was treated as satisfied by a...

CVE-2026-93602: Improper Check for Certificate Revocation

rustls-webpki versions before 0.103.10 and 0.104.0-alpha.5 contain faulty CRL authority-matching logic that compares only the first distributionPoint against each CRL's IssuingDistributionPoint, ignoring additional distributionPoints. Attackers with a compromised trusted issuing authority can...

RUSTSEC-2026-0285 TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level when they followed a key-changing message in the same record. For example, a plaintext EncryptedExtensions message packed into the same record as the ServerHello was accepted. RFC 8446 section 5.1 requires that handshak...

rustls-webpki: rustls-webpki: Denial of Service via crafted Certificate Revocation List

A flaw was found in rustls-webpki. A remote attacker, by influencing an application to parse a specially crafted Certificate Revocation List CRL that contains an empty onlySomeReasons value in its issuingDistributionPoint extension, could trigger a panic. This vulnerability leads to a denial of...

rustls v/0.23.44

Rustls is a modern TLS library written in Rust. Status Rustls is used in production at many organizations and projects. We aim to maintain reasonable API surface stability but the API may evolve as we make changes to accommodate new features or performance improvements. We have a roadmap for our...

curl: mbedTLS / wolfSSL / rustls backends silently skip hostname verification when CURLOPT_SSL_VERIFYPEER=0

Summary When an application sets CURLOPTSSLVERIFYPEER=0 while keeping CURLOPTSSLVERIFYHOST=2 the default, the mbedTLS, wolfSSL, and rustls TLS backends silently skip the hostname-vs-certificate check. The OpenSSL, GnuTLS, and Schannel backends correctly preserve hostname checking under the same...
