CVE-2026-1605 — Eclipse Foundation / Eclipse Jetty

Description (CNA)

In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed. This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response. In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak.

Affected (CNA)

Eclipse Foundation / Eclipse Jetty	affected 12.0.0 through 12.0.31; affected 12.1.0. through 12.1.5

A flaw was found in org.eclipse.jetty. A remote attacker can exploit this vulnerability by sending a compressed HTTP request with Content-Encoding: gzip when the server's response is not compressed. This prevents the release of the JDK Inflater, leading to a resource leak. This resource exhaustion can result in a Denial of Service (DoS), making the server unavailable to legitimate users.
