Vaadin and the October 2026 Node.js security releases

A deployed Vaadin application does not run Node.js, so it is not exposed to the vulnerabilities fixed in the Node.js security releases of 21 October 2026. Vaadin uses Node.js only to build the frontend and to run development mode, which means the exposure, where there is any, is in build and...

Improper Validation of Certificate with Host Mismatch

Overview Affected versions of this package are vulnerable to Improper Validation of Certificate with Host Mismatch via the checkServerIdentity function in lib/tls.js. An attacker can bypass certificate hostname checks by getting a TLS client to connect using fullwidth digits representing an IPv4...

CVE-2026-105483

Node.js tls.checkServerIdentity regression: a host written with fullwidth digits is not recognized as an IP address and is matched through the DNS/CN path after IDNA normalization, bypassing the certificate hostname check. Fixed in 24.22.1 and 26.12.1...

CVE-2026-106069

Node.js tls.checkServerIdentity normalizes non-canonical numeric hosts e.g. 0127.0.0.1 with domainToASCII before matching the certificate, while the platform resolver connects to a different address, allowing a TLS hostname check bypass. Fixed in 22.23.4, 24.22.1 and 26.12.1...

CVE-2026-107660

FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an improper certificate validation vulnerability in tlsopen of libavformat/tlsmbedtls.c, which skips hostname checks for IP-address hosts.
