Description

Replaces the MarkdownEditor on the Invoice "Terms" field with Filament's RichEditor, giving users real bold/italic/underline/lists/links/headings/tables/etc. formatting that actually renders instead of showing as literal text. Also:

• Sanitizes terms HTML on save (InvoiceObserver) using Filament's built-in HTML sanitizer, stripping <script> and other dangerous markup, and normalizes an emptied editor (<p></p>) back to null.
• Renders terms unescaped in the invoice PDF template now that it's sanitized at rest, so formatting shows up correctly.
• Applies the same rich-text toolbar to the "Default Invoice Terms" setting on both the Admin Settings page and the Company Settings page (previously a plain Textarea on the company panel), and made the field full-width on both.

Motivation and Context

Users couldn't use bold text or clickable links in Invoice Terms — the Markdown editor's output was HTML-escaped on the PDF, so any formatting appeared as literal text (e.g. **bold** instead of bold). Switching to a proper WYSIWYG editor and rendering its sanitized HTML output fixes this end-to-end, and aligns the two "Default Terms" settings fields with the same rich-text experience so prefilled terms are consistent with what the invoice form itself produces.

@KhawarMehfooz

Textarea::make(Setting::KEY_INVOICE_DEFAULT_FOOTER)

Shouldn't we then give the same treatment to the invoice footer?

[KhawarMehfooz]

@nielsdrost7, yes we should, but this issue was specific to terms that is why I only changed it's field.

[nielsdrost7]

@KhawarMehfooz Understood. If it's incredibly easy you can break the rule and otherwise it's a follow-up issue. I can merge later today, couple of hours

Before checking the scheme, it accounts for the obfuscation tricks that browsers silently undo when parsing an `href` value — HTML entity references (numeric like ` `/` ` and named like ` `/` ... ```php use Filament\Tables\Columns\TextColumn; use Illuminate\Support\Str; ... TextColumn::make(&`#39`;website&`#39`;) ->url(fn (string $state): ?string => Str::sanitizeUrl($state)) ... When rendering HTML content via methods like `html()` or `markdown()` on components such as `TextColumn` and `TextEntry`, Filament automatically sanitizes the output using Symfony&`#39`;s HtmlSanitizer component. This removes potentially dangerous elements like `` tags to help prevent XSS attacks. ... ### Sanitizing in Blade views ... When outputting rich text content (from a rich editor or Markdown editor) in your own Blade views, you are responsible for sanitizing it. You can use Filament&`#39`;s `sanitizeHtml()` string helper: ... ```blade {!! str($record->content)->sanitizeHtml() !!} ``` ... Never use `{!! $content !!}` with unsanitized user content. If you need to render Markdown as HTML, chain the helpers: ... ```blade {!! str($record->content)->markdown()->sanitizeHtml() !!} ``` <title>Rich editor - Filament</title> https://filamentphp.com/docs/5.x/forms/rich-editor By default, the editor outputs raw HTML, and sends it to the backend. Attackers are able to intercept the value of the component and send a different raw HTML string to the backend. As such, it is important that when outputting the HTML from a rich editor, it is sanitized; otherwise your site may be exposed to Cross-Site Scripting (XSS) vulnerabilities. When Filament outputs raw HTML from the database in components such as `TextColumn` and `TextEntry`, it sanitizes it to remove any dangerous JavaScript. However, if you are outputting the HTML from a rich editor in your own Blade view, this is your responsibility. One option is to use Filament’s `sanitizeHtml()` helper to do this, which is the same tool we use to sanitize HTML in the components mentioned above: ... ``` {!! str($record->content)->sanitizeHtml() !!} ``` ... If you’re storing content as ... your content requires processing to inject private image URLs or similar, you can use the content renderer to output HTML. This will automatically sanitize the HTML for you, so you don’t need to worry about it. ... The string returned from the `url()` closure is rendered directly into the `href` attribute of an ` ` tag, so if any part of the URL is built from user input you should make sure it cannot resolve to a scheme like `javascript:` or `data:` that the browser would execute. The simplest way to guarantee this is to wrap the return value in Filament’s `Str::sanitizeUrl()` helper, which only allows `http`/`https` and relative URLs: ... ``` use Illuminate\Support\Str; ->url(fn (string $id, string $label): ?string => Str::sanitizeUrl( route(&`#39`;users.show&`#39`;, $id), )) ``` ...

<title>Add Str::sanitize method for string sanitization</title> GitHub pull request 54285 in laravel/framework (link omitted to avoid creating a cross-reference) # Add Str::sanitize method for string sanitization - State: closed - Author: jannescb - Created: 2025-01-21T13:07:52Z - Updated: 2025-01-21T16:36:37Z - Repository: laravel/framework - Number: `#54285` - +50 -0 in 3 files - Merge commit: 54d322b06f3c8766082c56aae4d72865cfc9e5e6 --- This PR introduces a new `Str::sanitize` method. This helper provides a simple and effective way to sanitize strings, ensuring the removal of unsafe HTML elements and attributes. The method utilizes Symfony&`#39`;s HtmlSanitizer, with a default configuration to allow only safe elements. Developers can also provide a custom configuration for more granular control. For more details on the underlying sanitizer, see the Symfony documentation: Symfony HtmlSanitizer ## Basic Usage: ```php use Illuminate\Support\Str; use Symfony\Component\HtmlSanitizer\HtmlSanitizerConfig; // Basic sanitization Str::sanitize(&`#39`;Hello<script>alert("XSS")</script>&`#39`;); // Output: &`#39`;Hello&`#39`; // Custom configuration: allow relative media URLs $config = (new HtmlSanitizerConfig()) ->allowElement(&`#39`;img&`#39`;, &`#39`;src&`#39`;) ->allowRelativeMedias(); Str::sanitize(&`#39`;<img src="/does-not-exist.jpg" onerror="alert(\&`#39`;XSS\&`#39`;)" />&`#39`;, $config); // Output: &`#39`;<img src="/does-not-exist.jpg" />&`#39`; ``` ## Example Use Case The sanitize method can be used to prepare input for validation, as suggested in the Laravel documentation: Preparing Input For Validation. ```php use Illuminate\Support\Str; /** * Prepare the data for validation. */ protected function prepareForValidation(): void { $this->merge([ &`#39`;wysiwyg&`#39`; => Str::sanitize($this->wysiwyg), ]); } ``` This approach is particularly useful for cleaning up user-generated HTML content (e.g., from WYSIWYG editors) before validating or storing it, ensuring that only safe and sanitized content is processed. ## Outlook This feature could serve as the foundation for more advanced use cases, such as integrating automatic sanitization into Eloquent models via custom casts. For example, a `SanitizedHtml` cast could leverage `Str::sanitize` to ensure safe content is both stored and retrieved from the database. ## Timeline - someone committed - someone committed - Renamed from "Feature/str sanitize" to "Add Str::sanitize method for string sanitization" - someone committed - someone committed - someone committed **shaedrich** commented on 2025-01-21T14:14:32Z: > Not sure if we want to clutter the `Str` even more than it already is.

Use a supported HTML sanitizer.

Illuminate\Support\Str does not provide sanitizeHtml. The observer can reach this call for each non-null terms or footer value, so saving such an invoice can throw an undefined-method exception.

Suggested fix

-        $sanitized = Str::sanitizeHtml($html);
+        $sanitized = (string) str($html)->sanitizeHtml();

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	$sanitized = Str::sanitizeHtml($html);
	$sanitized = (string) str($html)->sanitizeHtml();

XSS

Reachability: External
Exploitability: Moderate
CWE: CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Backfill legacy invoice footers before raw rendering.

InvoiceService::renderHtml() uses this view for the on-screen preview. InvoiceObserver::saving() sanitizes only values saved after the observer runs. Existing footer values can therefore execute as active markup when another user opens the preview. Add an idempotent backfill before release, or sanitize the value at render time.
