CVE-2026-79650: Apache CXF OIDC relying-party open redirect after authentication

CVE-2026-79650 · Severity: medium · CVSS 6.1 · Published 2026-10-09

Apache CXF is a web services framework that includes OpenID Connect (OIDC) authentication support for protecting applications. A vulnerability in its relying-party component could allow an attacker to redirect authenticated users to a malicious website after they successfully log in, potentially leading to credential theft or further attacks. The flaw affects how redirect URLs are validated following successful authentication.

Technologies: Apache CXF. Vendors: Apache.

Technical details

The OIDC relying-party component fails to properly validate that decoded redirect URIs belong to the relying party's origin, instead preserving and using attacker-controlled state parameters as redirect targets. Both directly encoded and double-encoded external URLs can bypass the validation depending on which code path is executed. An unauthenticated attacker can craft a malicious request to trigger the open redirect after a user authenticates.

Affected products

Apache CXF versions before 3.6.13, 4.1.9, and 4.2.4
