CVE-2026-8384

Jetty Path Normalization Bug Returning Unresolved Paths

Published Jul 14, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
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.
