CVE-2026-1605

The exception handling code in Eclipse Jetty before version 9.2.9.v20150224 allows remote attackers to obtain sensitive information from process memory via illegal characters in an HTTP header, known as JetLeak.

In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode passwords as bytes, silently replacing characters outside that charset with '?'.

In Eclipse Jetty, a vulnerability has been identified involving incorrect path resolution for URIs containing semicolons. A request to a resource like '/public;/../admin/secret.txt' results in Jetty returning an unresolved path '/public/../admin/secret.txt' instead of the expected '/admin/secret.txt'. Jetty itself is not vulnerable because it does not serve files that fail the alias check, but web applications relying on Jetty's path resolution may be confused.

In Eclipse Jetty for HTTP/1, HTTP/2, and HTTP/3 requests, there is no strict check that the request authority (host and port) matches the value provided in the Host header (if present). This mismatch can cause problems such as incorrect URI construction, virtual host selection, reverse proxying, misleading logs, and others.

In Eclipse Jetty, the first HTTP/1.1 request with trailers causes the server to retain those trailers for subsequent requests on the same connection. Subsequent requests without trailers report the trailers from the first request, while requests with their own trailers report the union of the first and current request's trailers.

Eclipse Jetty has an HTTP/1.1 request smuggling vulnerability related to chunk extension handling, where the parser terminates chunk extension parsing at \r\n inside quoted strings instead of treating it as an error.

In Eclipse Jetty, the JASPIAuthenticator class sets ThreadLocal variables during authentication but fails to clear them on early return. A subsequent request on the same thread inherits these values, leading to broken access control and privilege escalation.
