CVE-2026-8384

Estado: AnalizadaMedia (5.3)—

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.
