CVE-2026-8384 Eclipse Jetty

Affected softwareEclipse Jetty
Severity5.3 Medium CVSS 3.1
Fixed in12.0.35, 12.1.9
WeaknessCWE-647
Published14 Jul 2026
Updated24 Oct 2026

Description

In Eclipse Jetty, an HTTP URI of this form: /public;/../admin/secret.txt results in an unresolved path of: /public/../admin/secret.txt instead of the expected: /admin/secret.txt Jetty itself is not affected, as it will not serve the secret.txt file because it will not pass the alias checker (only resolved resources are served). However, web applications that rely on resolved paths being provided by Jetty may be confused when receiving an unresolved path.

Decided by Exploit code for this candidate, published in a reviewed catalogue or a GitHub repository with 5 or more stars, or in use per CISA or VulnCheck; not only a CISA verdict, a forecast, or nothing at all
Finding This CVE is not listed in CISA KEV or VulnCheck KEV, CISA Vulnrichment records no active exploitation, no reviewed exploit catalogue carries an entry for it, and no GitHub PoC repository for it has 5 or more stars. Nobody has published exploit code worth tracing, so it is not a candidate for a rule ahead of the ones where somebody has; an upstream fix path does exist, so the remediation half of the candidacy still holds. This is a statement about what has been published, not about whether the defect is reachable or serious.
