The PDF Builder for WooCommerce. Create invoices,packing slips and more plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.0.11. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve invoice numbers, formatted invoice numbers, and creation timestamps for arbitrary WooCommerce orders by supplying any OrderNumber and InvoiceId values with a garbage nonce.
AnalysisAI
Missing authorization checks in the PDF Builder for WooCommerce WordPress plugin (all versions up to and including 2.0.11) allow any authenticated user holding Subscriber-level access or above to read invoice numbers, formatted invoice numbers, and creation timestamps for arbitrary WooCommerce orders by supplying attacker-chosen OrderNumber and InvoiceId values together with a garbage nonce. The prerequisite authentication is trivially met on stores that allow open customer registration, but the disclosure is confined to invoice metadata rather than full order or customer records, so impact is limited to low confidentiality (CVSS 4.3). …

Vulnerability AssessmentAI
| Exploitation | Requires (1) the WordPress site to run PDF Builder for WooCommerce version 2.0.11 or earlier, (2) WooCommerce with existing orders to enumerate, and (3) the attacker to hold at least a Subscriber-level authenticated account - trivially met on stores that permit open customer registration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a low-severity, low-real-risk information-disclosure flaw despite being tagged 'Authentication Bypass'. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed - the vendor trac changeset at https://plugins.trac.wordpress.org/changeset/3626297 contains the code correction, and administrators should apply the plugin update that incorporates it (i.e., upgrade PDF Builder for WooCommerce to the first release published after 2.0.11) rather than remaining on 2.0.11 or earlier; verify the applied version in the WordPress Plugins screen and cross-check against the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/1bbc24f8-ceb7-44c4-8691-7786cbb4f69b?source=cve. … Detailed patch versions, workarounds, and compensating controls in full report. |
