CVE-2026-13152 – Unauthenticated Privilege Escalation / Admin Takeover – Custom Fields Account Re…

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

Summary

CVE-2026-13152 is a high-severity unauthenticated privilege escalation vulnerability in the Custom Fields Account Registration For WooCommerce WordPress plugin, affecting all versions before 1.4. By exploiting insufficient validation in how custom registration fields are saved to user metadata, an unauthenticated attacker can register an account and assign themselves the WordPress administrator role, resulting in full site takeover. The IONIX research team is tracking potentially affected assets and recommends immediate patching.

Technical details

  • Root cause: The plugin saves user-submitted registration field values directly to WordPress user meta without adequately restricting which meta keys can be written. A prior fix introduced a blocklist intended to prevent fields from targeting the wp_capabilities meta key (which governs WordPress user roles), but the blocklist was anchored to the hardcoded wp_ prefix. On sites using a non-default database table prefix (e.g., shop_), the actual capabilities key is named {prefix}_capabilities — a value outside the blocklist’s scope — allowing the restriction to be bypassed entirely.
  • Trigger condition: The target WordPress installation must use a non-default database table prefix (i.e., $wpdb->prefix is set to any value other than wp_). A custom registration field must also be configured with a slug that maps to the capabilities meta key under that prefix.
  • Attack vector: Remote, unauthenticated. The attacker registers a new account via the standard WooCommerce My Account registration page, submitting a crafted field value that writes administrator to the user capabilities meta key. No prior authentication, user interaction, or special privileges are required.
  • Impact: Full administrator account takeover — the attacker gains unrestricted access to the WordPress admin panel, enabling arbitrary content modification, installation of malicious plugins, credential theft, and complete site compromise. CVSS impact metrics are rated High across Confidentiality, Integrity, and Availability.

Affected software

  • Custom Fields Account Registration For WooCommerce (WordPress Plugin) — all versions before 1.4

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector string: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
  • CWE: CWE-269 – Improper Privilege Management

Mitigation and recommended actions

  • Immediate: Update the Custom Fields Account Registration For WooCommerce plugin to version 1.4 or later. Version 1.4 resolves the vulnerability by comparing the reserved-slug blocklist against the site’s actual runtime database table prefix ($wpdb->prefix) rather than the hardcoded wp_ value, and adds an equivalent defense-in-depth check at the point each field value is written to user meta.
  • If immediate patching is not possible: Temporarily disable the plugin until the update can be applied. Additionally, consider restricting access to the WooCommerce registration endpoint at the network or WAF level to reduce the attack surface while remediation is planned.

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.
