Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The WooCommerce Multiple Customer Addresses & Shipping WordPress plugin before version 21.7 is affected by an authorization bypass vulnerability tracked as CWE-639. The plugin does not verify ownership of address records when performing add, update, retrieve, delete, or duplicate operations, allowing requests to succeed regardless of whether the acting user owns the data or holds high privileges.

Any authenticated user, including those assigned only subscriber rights, can exploit the flaw over the network to access, modify, duplicate, or remove address information belonging to other accounts. Successful exploitation yields full control over the targeted address data and carries a CVSS 3.1 score of 8.8.

Public advisories published via WPScan detail the affected plugin versions and recommend upgrading to 21.7 or later to correct the missing authorization checks. The associated EPSS score has remained low, with a current value of 0.0760 and a peak of 0.0880.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-639

Per-request decision making makes it harder to bypass authorization using user-controlled keys without proper validation in the decision process.

addresses: CWE-639

Consistent enforcement of approved authorizations makes bypassing via user-controlled keys ineffective.

A.5.15 directly requires defining and implementing access control rules (including authorization, need-to-know, role-based restrictions, formal requests, and consistency with classification) that stop one user from reaching another's data via a tampered key; the bounded remainder is dynamic or application-specific authorization logic (cross-referenced to 8.26) that may still allow bypass if those downstream rules are flawed.

Managing access rights includes ensuring users can only access their own records and not bypass authorization by altering identifiers.
