Overview

CVE-2026-8384 is a medium-severity vulnerability. It was published on July 14, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
