CVE-2026-27017

CVE-2026-27017 affects the uTLS fork of crypto/tls ( Versions 1.6.0–1.8.0 ) with GREASE ECH, causing a fingerprint mismatch with Chrome due to inconsistent cipher-suite selection between the outer ClientHello and ECH. Specifically, uTLS hardcodes AES for the outer cipher suite while randomly sele...

CVE-2026-27017

uTLS is a fork of crypto/tls, created to customize ClientHello for fingerprinting resistance while still using it for the handshake. Versions 1.6.0 through 1.8.0 contain a fingerprint mismatch with Chrome when using GREASE ECH, related to cipher suite selection. When Chrome selects the preferred...

uTLS 安全漏洞

uTLS is an open-source Go language codebase developed by Refraction Networking. Versions 1.6.0 to 1.8.0 of uTLS contain security vulnerabilities. These vulnerabilities stem from inconsistent password selection logic when using GREASE ECH, which may lead to fingerprint mismatches...

GHSA-RRXV-PMQ9-X67R uTLS has a fingerprint vulnerability from missing padding extension for Chrome 120

The padding extension was incorrectly removed in utls for the non-pq variant of Chrome 120 fingerprint. Chrome removed this extension only when sending pq keyshares. Only this fingerprint is affected since newer fingerprints have pq keyshares by default and older fingerprints have this extension...

GHSA-7M29-F4HW-G2VX uTLS has a fingerprint vulnerability from GREASE ECH mismatch for Chrome parrots

There is a fingerprint mismatch with Chrome when using GREASE ECH, having to do with ciphersuite selection. When Chrome selects the preferred ciphersuite in the outer ClientHello and the ciphersuite for ECH, it does so consistently based on hardware support. That means, for example, if it prefers...
