CVE-2026-46581: Eclipse Mojarra

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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`.

Affected products

• Eclipse Mojarra: from 2.3.0, up to and including 4.1.13; version 5.0.0 only
