Detailsinfo

A vulnerability has been found in OmniFaces up to 1.14.2/2.7.32/3.14.22/4.7.11/5.4.1 and classified as critical. This vulnerability affects an unknown code of the component CombinedResourceHandler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

OmniFaces is a utility library for Faces. In OmniFaces versions before 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2, CombinedResourceHandler accepts a structurally valid deflated and base64 encoded combined resource ID without verifying that the server issued it. A forged ID can cause unbounded decoded output, add unique reconstructed IDs to a process-lifetime cache, or combine resources other than stylesheets and scripts. Because jakarta.faces.RESOURCE_EXCLUDES is not applied by this custom resolution path, a forged ID can disclose Facelets source from the webapp resource tree or META-INF/resources. In a deployment configured with the wildcard CDN mapping, a forged ID that selects omnifaces.graphic can also cause a blind, deployment-dependent server-side fetch whose destination derives partly from the request Host header. The flaw does not provide arbitrary file read or establish arbitrary-scheme or arbitrary-destination SSRF. The shared authenticity failure permits memory exhaustion and limited resource disclosure. This issue is fixed in versions 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-102695 since 09/29/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.

Upgrading to version 1.14.3, 2.7.33, 3.14.23, 4.7.12 or 5.4.2 eliminates this vulnerability.
