CVE-2026-8384: Eclipse Jetty

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Eclipse Jetty: from 12.0.0, before 12.0.35 (fixed in 12.0.35); from 12.1.0, before 12.1.9 (fixed in 12.1.9)
