CVE-2026-41883
HighSummary
OmniFaces, a utility library for Faces, prior to versions 1.14.2, 2.7.32, 3.14.16, 4.7.5, and 5.2.3, contains a server-side EL injection vulnerability leading to Remote Code Execution (RCE). An attacker can craft a resource request URL containing an EL expression in the resource name, which is evaluated server-side.
Risk Assessment
This vulnerability can lead to remote code execution, posing a serious threat to the security of applications and organizational data. An attacker could exploit this flaw to gain control over the system.
Recommendation
It is recommended to upgrade to versions 1.14.2, 2.7.32, 3.14.16, 4.7.5, or 5.2.3 to mitigate this vulnerability. Existing applications should also be reviewed for the use of CDNResourceHandler with wildcard CDN mapping.

Original NVD description (English source)
OmniFaces is a utility library for Faces. Prior to versions 1.14.2, 2.7.32, 3.14.16, 4.7.5, and 5.2.3, there is a server-side EL injection leading to Remote Code Execution (RCE). This affects applications that use CDNResourceHandler with a wildcard CDN mapping (e.g. libraryName:*=https://cdn.example.com/*). An attacker can craft a resource request URL containing an EL expression in the resource name, which is evaluated server-side. This issue has been patched in versions 1.14.2, 2.7.32, 3.14.16, 4.7.5, and 5.2.3.
