CVE-2026-42505 Invoking Encrypted Client Hello privacy leak in crypto/tls

Handshakes which used Encrypted Client Hello could be de-anonymized by a passive network observer due to a disclosure of pre-shared key identities in the unencrypted client hello...

crypto/tls: golang: Go crypto/tls: Information disclosure in Encrypted Client Hello

A flaw was found in the crypto/tls package in Go. Handshakes utilizing Encrypted Client Hello ECH could lead to de-anonymization by a passive network observer. This is due to the disclosure of pre-shared key identities within the unencrypted client hello, allowing an attacker to potentially link...

Flawed TLS Implementations Leak RSA Keys

A number of TLS software implementations contain vulnerabilities that allow hackers with minimal computational expense to learn RSA keys. Florian Weimer, a researcher with Red Hat, last week published a paper called “Factoring RSA Keys With TLS Perfect Forward Secrecy” that demonstrated...
