Be the first to know when new zero-days emerge:

Summary

CVE-2026-61466 is a critical privilege-escalation vulnerability in the OAuth2 Dynamic Client Registration endpoint of Apache CXF (org.apache.cxf:cxf-rt-rs-security-oauth2). The endpoint fails to validate the requested scope parameter against an allowlist of predefined authorization scopes, allowing a client to self-assign elevated privileges during registration. It carries a CVSS v3.1 base score of 9.1 (Critical).

Technical details

  • Root cause: The authorization server accepts and stores scope values verbatim from client registration requests without enforcing compliance with predefined authorization scopes (CWE-304: Missing Critical Step in Authentication).
  • Trigger conditions: An attacker sends a request to the OAuth2 Dynamic Client Registration endpoint specifying arbitrary, elevated scopes.
  • Attack vector: Network-accessible, low attack complexity, no privileges and no user interaction required (AV:N/AC:L/PR:N/UI:N).
  • Impact: A client can register with elevated privileges it should not be granted, resulting in high impact to confidentiality and availability.

Affected software

  • Apache CXF versions before 3.6.12 (fixed in 3.6.12)
  • Apache CXF versions 4.0.0 through 4.1.7 (fixed in 4.1.8)
  • Apache CXF versions 4.2.0 through 4.2.2 (fixed in 4.2.3)

Severity

  • CVSS v3.1 base score: 9.1 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

Mitigation and recommended actions

  • Immediate: Upgrade to a fixed release — 3.6.12, 4.1.8, or 4.2.3 — matching your current branch.
  • If no patch: Restrict or disable the OAuth2 Dynamic Client Registration endpoint, and place the authorization server behind network controls that limit registration requests to trusted callers until the upgrade can be applied.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
