HDWebmobile Size Charts
Add size charts to product categories — edited only through a capability- and nonce-checked admin form.
Overview
HDWebmobile Size Charts lets you build size-guide tables (Size / Bust / Waist / Hips, or whatever columns you choose) and assign each one to one or more product categories. A “Size chart” disclosure appears automatically on matching product pages. Any individual product can override its category’s chart from its own Product data panel.
“Product Size Charts for WooCommerce” (versions up to and including 2.4.5) shipped CVE-2025-23991 (CWE-862 Missing Authorization): the chart-configuration write path had no capability check, letting it be changed by users who should never have been able to touch store-wide content. This plugin closes that by construction: there is one write path, properly gated — the chart-save method is called from exactly one place, the settings-save handler, which checks current_user_can('manage_woocommerce') and a verified nonce before a single field is read. There is no image upload anywhere — a chart is only ever a table of admin-typed text (column headers and rows), so there’s nothing file-shaped in this plugin for a write-path bug to touch. Every value is validated regardless of caller: category assignments are checked against real, existing category terms, every cell is sanitised text, and a chart with no name, columns, or rows is silently skipped rather than guessed at.
