EUVD-2026-58670
A flaw was found in Undertow, an HTTP server, within its HTTP response header writing path. The writeString method performs a silent narrowing cast from 16-bit Unicode characters to 8-bit bytes when writing HTTP response header values. A remote attacker can exploit this by supplying specific...
CVE-2026-19879
Undertow contains a vulnerability in the HTTP response header writing path: the writeString() method narrows 16‑bit Unicode to 8‑bit bytes when writing header values, which can truncate characters to ASCII control/symbols and cause limited integrity impact or information disclosure if input isn’t...

undertow: undertow-websockets: Undertow: Pre-Auth DoS on websocket endpoint with @ServerEndpoint class with any @OnMessage method
A flaw was found in Undertow. A remote attacker can cause Out of Memory on websockets endpoint without authentication on any @ServerEndpoint class that has any @OnMessage method. This allows an attacker to cause Denial of Service attack without authentication and using only a standard WebSocket...
undertow-core: Undertow: Authentication Bypass via AJP ssl_cert/is_ssl Forgery
the Undertow AJP listener honours forged sslcert and isssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP...
