Vulnerability Details & Mitigation

What is CVE-2026-54847 and which versions of Stylish Cost Calculator are affected?

CVE-2026-54847 is a high-severity unauthenticated broken access control vulnerability (CWE-862: Missing Authorization) in the Stylish Cost Calculator WordPress plugin. All versions up to and including 8.3.9 (both free and premium editions) are affected. The vulnerability allows remote, unauthenticated attackers to access privileged plugin functionality without user interaction, exposing sensitive business and customer data collected via quote, lead, and cost estimation forms. Source: NIST CVE-2026-54847, June 29, 2026. Note: Integrity and availability are not directly impacted; only confidentiality is at risk.

How can organizations mitigate CVE-2026-54847?

To mitigate CVE-2026-54847, organizations should immediately update the Stylish Cost Calculator plugin to version 8.3.10 or later (current release: 8.4.3) via the WordPress Plugin Repository or the WordPress admin dashboard under Plugins → Updates. If immediate patching is not feasible, restrict network access to the WordPress admin-ajax.php handler and plugin-specific REST API routes at the web application firewall or reverse proxy layer. Additionally, audit WordPress access logs for unexpected or anonymous requests to plugin-related endpoints prior to patching. Note: Delaying patching increases the risk of unauthorized data exposure.

IONIX Platform Capabilities for Zero-Day and CVE Response

How does IONIX detect and validate exposures to new zero-days like CVE-2026-54847?

IONIX's External Exposure Management platform continuously maps the entire external attack surface using multi-factor discovery methods such as DNS analysis, certificate mapping, and metadata inspection. For zero-days like CVE-2026-54847, IONIX analyzes dozens of threat intelligence feeds with agentic technology to detect proof-of-concept code, exploit kits, and indicators of active targeting. The platform applies AI to proactively evaluate exploitability, filters vulnerabilities by attacker-centric criteria, and transforms real-world PoCs into safe, non-intrusive test payloads for validation in production environments. This ensures rapid, accurate identification and validation of exploitable exposures. Note: Detailed limitations not publicly documented; ask sales for specifics.

CVE-2026-54847 – Unauthenticated Broken Access Control – Stylish Cost Calculator WordPress Plugin…

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

Summary

CVE-2026-54847 is a high-severity Unauthenticated Broken Access Control vulnerability (CWE-862: Missing Authorization) affecting the Stylish Cost Calculator WordPress plugin in all versions up to and including 8.3.9. With a CVSS v3.1 base score of 7.5 (HIGH), the flaw can be exploited remotely by unauthenticated attackers with no user interaction required, resulting in unauthorized access to protected plugin functionality and significant confidentiality impact. Sites using this plugin for quote generation, lead capture, and cost estimation forms are at risk of exposing the business and customer data those forms collect.

Technical details

  • Root cause: A missing authorization check within a plugin function fails to validate whether the requesting user has the required permissions before executing privileged operations. No nonce token verification is performed, allowing the access control boundary to be bypassed entirely.
  • Trigger conditions: The vulnerability is exploitable by any unauthenticated network-adjacent or remote attacker. No credentials, session tokens, or prior site interaction are needed.
  • Attack vector: Network-based (AV:N). The vulnerable function is reachable over standard HTTP/HTTPS without authentication (PR:N) and without any victim interaction (UI:N).
  • Impact: Confidentiality impact is rated HIGH (C:H). Successful exploitation enables unauthorized actors to invoke privileged plugin operations. Given the plugin’s role in collecting quote submissions, lead generation data, customer contact details, and file uploads, this class of access control failure exposes sensitive business and personal information to unauthenticated parties. Integrity and availability are not directly impacted (I:N, A:N).

Affected software

  • Stylish Cost Calculator (WordPress plugin, free edition) — all versions <= 8.3.9
  • Stylish Cost Calculator Premium — versions <= 8.3.9

Severity

  • CVSS v3.1 Base Score: 7.5 (HIGH)
  • Vector string: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate action — update the plugin: Upgrade the Stylish Cost Calculator plugin to version 8.3.10 or later (current release: 8.4.3). The fix is available directly from the WordPress Plugin Repository and via the WordPress admin dashboard under Plugins → Updates.
  • Audit lead/quote data access: Review WordPress access logs for unexpected or anonymous requests to plugin-related admin-ajax endpoints or plugin REST routes that predate the patch, as a precaution against prior unauthorized access.
  • If immediate patching is not feasible: Restrict network access to the WordPress admin-ajax.php handler and any plugin-specific REST API routes at the web application firewall or reverse proxy layer to reduce exposure until the plugin can be updated.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
