CVE-2026-44930: Apache CXF: LDAP Injection vulnerability in XKMS LDAP Repository

An LDAP injection vulnerability in the LDAP Certificate repository of the XKMS server in Apache CXF may allow an attacker to retrieve arbitrary certificates from the repository.  Users are recommended to upgrade to versions 4.2.1, 4.1.6 or 3.6.11, which fix this issue.

Security readout for executives and security teams

Plain-English summary

Apache CXF’s XKMS LDAP certificate repository can be manipulated through LDAP injection. A remote unauthenticated attacker may retrieve certificates that should not be accessible. The sources describe confidentiality impact, not system takeover, data modification, or service disruption.

Executive priority

Treat this as a high-priority confidentiality issue for any internet-facing or partner-facing CXF XKMS deployment. Patch promptly where the LDAP repository is in use; deprioritize only after confirming the affected component is absent or not enabled.

Technical view

CVE-2026-44930 is CWE-90 in Apache CXF’s XKMS LDAP Certificate repository, package org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap. CVSS 3.1 is 7.5: network, low complexity, no privileges, no user interaction, high confidentiality impact only.

Likely exposure

Exposure is likely limited to Apache CXF deployments that run the XKMS server with the LDAP Certificate repository component. The source bundle lists Apache CXF versions including 4.2.0, 4.0.0, and 0, with fixed versions 4.2.1, 4.1.6, and 3.6.11.

Exploitation context

The CVE is not listed as KEV in the provided bundle, and no supplied source states active exploitation. The risk is still material because the CVSS vector indicates remote unauthenticated access with low attack complexity and high confidentiality impact.

Researcher notes

The supplied evidence identifies arbitrary certificate retrieval, not write access or denial of service. Affected-version granularity is limited in the bundle, so researchers should rely on Apache advisory details and vendor package mapping before declaring individual products affected.

Mitigation direction

  • Upgrade Apache CXF to 4.2.1, 4.1.6, or 3.6.11.
  • Prioritize systems exposing XKMS services over a network.
  • Identify uses of cxf-services-xkms-x509-repo-ldap in application dependencies.
  • Review Apache and Red Hat guidance for product-specific packaging status.
  • If immediate upgrade is blocked, reduce exposure until vendor guidance is applied.

Validation and detection

  • Inventory Apache CXF versions in deployed applications and build manifests.
  • Confirm whether the XKMS server LDAP Certificate repository is enabled.
  • Check for dependency org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap.
  • Verify upgraded deployments report a fixed Apache CXF version.
  • Review certificate repository access logs for unusual retrieval patterns.
