Miggo AIRoot Cause Analysis

The vulnerability stems from two key issues: 1) Insufficient input sanitization when saving TinyMCE-generated content (handled by AdminCmsContentController's save process), and 2) Improper TinyMCE configuration allowing event attributes. Low-privileged users could inject XSS via TinyMCE's HTML mode, and the lack of output encoding when rendering stored content exacerbated the issue. The fix in v1.4.11 likely involved updating TinyMCE and adding server-side sanitization.
