CVE-2026-102695: OmniFaces unauthenticated resource ID forging in CombinedResourceHandler

CVE-2026-102695 · Severity: high · CVSS 8.2 · Published 2026-10-14

OmniFaces is a utility library for JavaServer Faces applications that combines web resources like stylesheets and scripts. The CombinedResourceHandler component fails to verify that combined resource IDs were actually issued by the server, allowing attackers to forge IDs that cause memory exhaustion, disclose Facelets source code from the application, or trigger server-side fetches to attacker-influenced destinations.

Technologies: OmniFaces. Vendors: OmniFaces.

Technical details

CombinedResourceHandler accepts deflate+base64 encoded combined resource IDs without authenticity verification. Attackers can forge IDs to trigger unbounded decompression (leading to memory exhaustion), bypass jakarta.faces.RESOURCE_EXCLUDES to access Facelets sources and META-INF/resources, or exploit wildcard CDN mappings to cause blind server-side fetches with Host-header-derived destinations. The vulnerability does not enable arbitrary file read or arbitrary-scheme SSRF.

Affected products

  • OmniFaces OmniFaces before 1.14.3, 2.7.33, 3.14.23, 4.7.12, and 5.4.2
