CVE-2026-8678: CWE-862 Missing Authorization in richardperdaan MyParcel
The MyParcel plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.25.1. 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 view and modify shipment options — including carrier, delivery type, package type, number of labels, weight, signature requirement, and insurance — on any arbitrary order.
AI Analysis
Technical Summary
CVE-2026-8678 is an authorization bypass vulnerability in the MyParcel plugin for WordPress, affecting all versions up to and including 4.25.1. The plugin fails to properly verify user authorization before allowing modifications to shipment options on arbitrary orders. This allows authenticated users with low privileges (subscriber-level and above) to alter shipment details such as carrier, delivery type, package type, label count, weight, signature requirement, and insurance. The CVSS 3.1 base score is 4.3, reflecting a medium severity with network attack vector, low attack complexity, and requiring low privileges but no user interaction.
Potential Impact
Authenticated users with subscriber-level access or higher can bypass authorization controls to modify shipment options on any order. This can lead to unauthorized changes in shipping configurations, potentially disrupting order fulfillment or causing logistical issues. There is no direct confidentiality or availability impact reported, but integrity of shipment data is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Until a patch is available, restrict user roles and permissions to limit access to trusted users only. Monitor for updates from the vendor regarding an official fix.
