CVE-2026-81427
MediumCVSS 4.3Summary
The WC Vendors WordPress plugin before 2.7.2.1 does not verify that the vendor submitting a front-end order shipment status change owns the referenced order, allowing any authenticated vendor to mark another vendor's order as shipped, add an order note falsely attributed to the victim vendor, and trigger the customer shipment notification email.
Risk Assessment
Vendors can manipulate other vendors' order statuses, potentially leading to fraud, customer deception, and loss of trust in the platform.
Recommendation
Update the WC Vendors plugin to version 2.7.2.1 or later which includes the fix. Additionally, implement ownership verification mechanisms for orders.
Other vulnerabilities in WC Vendors
See all- CVE-2026-81428Medium
The WC Vendors WordPress plugin before 2.7.2.1 does not verify ownership or the object type of user-supplied IDs when saving product variations, allowing authenticated users with the vendor role to modify product variations belonging to other vendors, and to change the status and title of arbitrary posts, via IDOR.
- CVE-2026-81426Medium
The WC Vendors WordPress plugin before 2.7.2.1 does not have CSRF protection on some of its front-end order shipment status actions, which could allow attackers to make a logged-in vendor change the shipment status of their own orders via a crafted request.
- CVE-2026-15351Medium
The WC Vendors plugin for WordPress up to version 2.7.0 is vulnerable to generic SQL Injection via the 'status' parameter. Insufficient escaping and lack of query preparation allow authenticated attackers with shop manager-level access and above to append additional SQL queries, potentially extracting sensitive information from the database.
