Doc Text:	A flaw was found in Eclipse Jetty. An attacker could craft a specially formed HTTP Uniform Resource Identifier (URI) that, when processed by Jetty, results in an unresolved path. While Jetty itself is not directly affected, web applications relying on Jetty to provide resolved paths may be confused, potentially leading to unintended information disclosure. This could allow an attacker to access sensitive files or directories that should otherwise be protected.	Story Points:	---

Description OSIDB Bzimport 2026-07-14 10:01:42 UTC

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.
