Eclipse Mojarra code injection

7.5 HIGHPublic exploitEPSS 0.56%
  1. Published5 Aug 2026

Description

In Eclipse Mojarra versions 2.3 and following, URL handing in `DefaultFaceletFactory` does not properly sanitize and/or block remote URLs, allowing an attacker to specify a URL to a remote Facelet which will be included and processed as part of the normal request, with the privileges of the target server. This could allow access to restricted files such as `WEB-INF/web.xml` or `/etc/passwd`.
