Miggo AIRoot Cause Analysis

The vulnerability stems from improper input sanitization in the placeholder handling code. The commit diff shows the fix added escapeHTML() around input.getAttribute('placeholder'). Before the patch, the code in Tagify's initialization prototype (line 104 of src/tagify.js) directly used user-controlled placeholder values from input attributes without sanitization, making it vulnerable to XSS payload injection. The vulnerability is clearly located in the initialization logic that processes input attributes, specifically the placeholder handling path.
