Summary

CVE-2026-84238 is an unauthenticated broken access control vulnerability (CWE-862: Missing Authorization) in the YITH Request a Quote for WooCommerce Premium WordPress plugin. It affects all versions prior to 4.46.0 and carries a CVSS v3.1 base score of 9.8 (Critical), as it can be exploited remotely without authentication or user interaction.

Technical details

  • Root cause: The plugin fails to enforce proper authorization checks (Missing Authorization, CWE-862) on one or more of its functions.
  • Trigger conditions: No authentication or special privileges are required to reach the affected functionality; no user interaction is needed.
  • Attack vector: Network — an attacker can send requests directly to the vulnerable WordPress/WooCommerce site over the internet.
  • Impact: The CVSS vector (C:H/I:H/A:H) indicates the flaw can fully compromise confidentiality, integrity, and availability of affected data/functionality on the site.

Affected software

  • YITH Request a Quote for WooCommerce Premium — all versions prior to 4.46.0

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Update the YITH Request a Quote for WooCommerce Premium plugin to version 4.46.0 or later.
  • If no patch can be applied immediately: Restrict access to the plugin’s endpoints via a web application firewall, and monitor for anomalous unauthenticated requests to WooCommerce/quote-related plugin functions until the update 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.
