# Version 9.1.257 (28 September 2026)

#### **Ruleset Management**

##### Enable YouTube embeds in the rich text editor (#153294)

**Problem**

- Unable to embed YouTube videos in widgets and help files

**Solution**

- This update broadens the Content-Security-Policy to allow YouTube iframe sources and disables the Syncfusion HTML sanitiser in the rich text editor so embedded video content can load without CSP blocking.
- It preserves the existing allowances for app assets and Syncfusion resources while enabling video embeds in editor content.
