Vulnerability	Vulnerable Version
M Improper Validation of Consistency within Input org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine. Affected versions of this package are vulnerable to Improper Validation of Consistency within Input through `ComplianceUtils.verify(HttpURI, HttpFields, HttpCompliance, ComplianceViolation.Listener)` in `jetty-core/jetty-http/src/main/java/org/eclipse/jetty/http/ComplianceUtils.java`. An attacker can bypass host consistency checks by sending a request whose `:authority` pseudo-header and `Host` header name different hosts, causing Jetty to accept the request and expose conflicting host identities to different code paths. This lets attacker-controlled host information survive inside the request, so logic that relies on `Request.getServerName()` or the URI authority can see one host while code reading the raw `Host` header sees another. In deployments that use host-based routing, ACLs, redirects, or tenant isolation, this can lead to incorrect request handling, host-based access control bypass, and attacker-influenced URL generation or logging. Notes HTTP/1.1 already had its own authority/Host consistency path in `HttpConnection`/`HttpChannelState`; the gap was in the HTTP/2 and HTTP/3 server entry flow where the shared compliance check was invoked before that comparison happened. The mismatch check only rejects when both values are present and differ after normalizing case and default ports, so requests with only one of `:authority` or `Host` present are not part of this issue.

M Interpretation Conflict org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine. Affected versions of this package are vulnerable to Interpretation Conflict due to inconsistent handling of invalid or unusual URIs in the `parse()` function on `HttpURI.java‎`.

Affected versions of this package are vulnerable to Improper Resource Shutdown or Release due to an error in handling gzip compression in the `GzipHandler`.

L Information Exposure org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine. Affected versions of this package are vulnerable to Information Exposure such that nonstandard cookie parsing may allow an attacker to smuggle cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie parsing mechanism.

Exploiting this vulnerability results in cookies exfiltration and policy based on cookies bypass. Note: A cookie header such as: `DISPLAY_LANGUAGE="b; JSESSIONID=1337; c=d"` will be parsed as one cookie, with the name `DISPLAY_LANGUAGE` and a value of `b; JSESSIONID=1337; c=d` instead of 3 separate cookies.

Affected versions of this package are vulnerable to Denial of Service (DoS) such that servlets with multipart support (e.g. annotated with `@MultipartConfig`) that call `HttpServletRequest.getParameter()` or `HttpServletRequest.getParts()` may cause `OutOfMemoryError` when the client sends a multipart request with a part that has a name but no filename and very large content. Note: This happens even with the default settings of `fileSizeThreshold=0`, which should stream the whole part content to disk.
