CVE-2026-46581 (opens in a new tab)How to fix?
Upgrade org.glassfish:jakarta.faces to version 4.0.22, 4.1.13 or higher.
Overview
org.glassfish:jakarta.faces is an Oracle's implementation of the JavaServer Faces specification.
Affected versions of this package are vulnerable to Remote Code Execution due to path traversal in the resolveURL(URL source, String path) method of DefaultFaceletFactory, which passes a path that does not start with / straight into the URL constructor, so an absolute spec overrides the base URL. An attacker can execute code server-side by supplying an absolute URL such as http://attacker.example/rce.xhtml that Mojarra fetches, compiles, and evaluates as a Facelet including its #{...} EL expressions, or read arbitrary files through file:// and jar:file:// schemes. This requires the application to have a JSF page whose <ui:include src>, <ui:composition template>, or <ui:decorate template> value comes from user-controlled input, for example <ui:include src="#{param.p}" />.
