Protect content in the React Rich Text Editor with XSS prevention, content sanitization, HTML encoding, trusted resource controls, and standards-compliant output. Maintain content integrity, enforce security best practices, and support regulatory and organizational compliance requirements.

React Rich Text Editor CSP support

CSP support for editor assets

Load editor styles, fonts, and images only from approved origins to comply with Content Security Policy headers without extra configuration. Use it in regulated apps where every asset must trace back to a trusted source.

React Rich Text Editor XHTML output

Standards-compliant XHTML output

Produce properly closed elements and standardized attributes that round-trip through XML pipelines and validation tooling without manual cleanup. Use it in publishing workflows where markup must remain portable across CMS, email, and feed systems.

React Rich Text Editor XSS protection

XSS prevention and content sanitization

Strip unsafe scripts, event handlers, and malicious markup from pasted or imported content with configurable sanitization rules that help protect applications from untrusted HTML. Use it on public forms, community platforms, and content submission portals where users can paste HTML content.

React Rich Text Editor secure HTML encoding

HTML encoding for safe storage

Encode HTML content to preserve rich text formatting during storage, processing, and data transfer while reducing the risk of unintended script execution. Use it when formatted content is exchanged between applications and services that require secure HTML handling.
