description
WebToffee WooCommerce PDF Invoices, Packing Slips, Delivery Notes & Shipping Labels versions through 4.9.8 are affected by a path-traversal flaw. An authenticated user with subscriber-level access or greater may obtain server file contents through invoice output functions, subject to access to the required invoice request values.
mitigation
Disable or remove the affected plugin where possible, especially on sites that allow untrusted accounts. Until a vendor-fixed release is confirmed, restrict subscriber account creation and limit access to invoice print and download functionality.
outcome
Upstream: a detection for this already ships elsewhere, so we didn't generate a new one. The credit goes to whoever did.
