EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 90% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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 what provided in the Host header (if present).

This was not enforced in earlier HTTP RFC (for example, in RFC 2616), but it is in the latest RFC (9110 and 9112).

This mismatch can cause a number of problems that may be classified as vulnerabilities such as:

* URI constructions (for example, for redirects -- this is typical for login pages)

* Virtual host selection

* Reverse proxying

* Misleading logs

* Etc.

Given that the latest RFCs require that request authority and Host header must match, Jetty should enforce this invariant.
