CVE-2026-1605

HIGHPre-NVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 54% 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).

A fix is available — apply it.

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.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
