Vulnerability scanners answer a different question than supply chain attacks ask. 208 threads describe compromise arriving through install scripts.

Two different teams describe the same failure: thousands of alerts, no correlation, and humans who stopped reading them. 209 threads, and no product owns it.

Combining two orders through a draft creates a third one, double-commits stock, and inflates revenue. 42 threads describe the cleanup nobody automated.

Secret scanners tell you a key was exposed. 106 threads describe the harder question: which leaked keys are still live, and what can they reach?
Shopify proof approval workflow for custom orders
Custom-product shops approve artwork by email, then production guesses which version was signed off. 198 threads describe the same rework loop.
