[high] Incorrect JavaScript string escaping in copy functionality The JavaScript string escaping in the copy button implementation doesn't properly handle all cases that could break the generated JavaScript. Specifically, if the copied text contains a single quote followed by a backslash, it will result in malformed JavaScript. For example, if Suggested fix: Use a proper JavaScript string escaping function or encode the value using a more robust method like JSON.stringify instead of manual replacement. Alternatively, use a template literal approach with proper escaping. *Scanner: code-review/logic | * **[high] Incorrect JavaScript string escaping in copy functionality**
The JavaScript string escaping in the copy button implementation doesn't properly handle all cases that could break the generated JavaScript. Specifically, if the copied text contains a single quote followed by a backslash, it will result in malformed JavaScript. For example, if `value` is "It\'s a test", the escaped version becomes "It\\\'s a test" which when embedded in the JS string literal becomes: navigator.clipboard.writeText('It\\\'s a test') - this will not work correctly because the single quote is not properly escaped within the JS string.
Suggested fix: Use a proper JavaScript string escaping function or encode the value using a more robust method like JSON.stringify instead of manual replacement. Alternatively, use a template literal approach with proper escaping.

[medium] Inconsistent error handling in copy button The CopyButton component uses Suggested fix: Add proper error handling around the clipboard operation. Consider using a more robust approach like calling a JS function that returns a promise and handling both success and failure cases. *Scanner: code-review/convention | * **[medium] Inconsistent error handling in copy button**
The CopyButton component uses `document::eval(&js)` which can fail silently. If the JavaScript execution fails, the UI will still show 'Copied!' but the actual copy operation may have failed. The component should handle potential errors from the clipboard API and provide appropriate feedback to the user.

[high] Potential XSS via Copy Button The CopyButton component directly interpolates user-provided 'value' into JavaScript code without proper sanitization. Although the code attempts to escape single quotes and backslashes, it's insufficient to prevent XSS when the value contains malicious JavaScript. An attacker could inject a value like "'; alert(1); //" which would result in executable JavaScript being evaluated by navigator.clipboard.writeText(). This allows for potential XSS exploitation through the copy functionality. Suggested fix: Use a more robust escaping mechanism or sanitize the input before inserting into JavaScript. Consider using a library specifically designed for HTML/JS escaping, or ensure all user inputs are properly encoded according to JavaScript string literal rules.

[high] Potential XSS via Copy Button The CopyButton component directly incorporates user-provided 'value' into JavaScript code without proper sanitization. While the code attempts to escape certain characters, it's insufficient to prevent XSS when the value contains malicious content that could be interpreted as JavaScript when executed in the browser context. Suggested fix: Use a more robust escaping mechanism or avoid inline JavaScript execution entirely. Consider using a safer method like creating a temporary textarea element and using document.execCommand('copy') instead of navigator.clipboard.writeText().

[medium] Complex boolean expression in conditional rendering The conditional rendering logic uses a complex boolean expression with multiple nested conditions that could be simplified for better readability and reduced bug risk. The 'if copied()' condition is used both for determining the button's icon and for setting the title attribute. Suggested fix: Extract the conditional logic into separate variables or functions to make the intent clearer and reduce the chance of errors when modifying the component behavior. *Scanner: code-review/complexity | * **[medium] Complex boolean expression in conditional rendering**

[medium] Inconsistent async timeout handling The component uses different async timeout mechanisms for web vs non-web targets (gloo_timers vs tokio). This creates inconsistent behavior between platforms and could lead to timing issues or compilation errors on non-web targets. Suggested fix: Standardize on one async runtime or ensure consistent behavior across platforms by using platform-agnostic alternatives. *Scanner: code-review/convention | * **[medium] Inconsistent async timeout handling**

The CopyButton component uses `document::eval(&js)` to execute JavaScript for copying to clipboard, but doesn't handle potential errors from the clipboard API. If the clipboard operation fails (which can happen due to browser permissions or other restrictions), the UI will still show success (copied state) without any indication of failure.

[medium] Deeply nested control flow in async block The async block contains nested conditional compilation directives (#cfg) which creates a complex control flow path that's difficult to reason about. The branching logic between web and non-web platforms is embedded within an async context, making it harder to follow the execution path.

[medium] Inconsistent async behavior between web and non-web targets The CopyButton component uses different async mechanisms for different targets (gloo_timers::future::TimeoutFuture for web, tokio::time::sleep for non-web). This inconsistency could lead to different timing behaviors or potential runtime errors if the non-web target doesn't have tokio available or if the async runtime isn't properly configured. Suggested fix: Standardize on a single async approach or ensure both paths are properly handled with appropriate feature detection and fallbacks. *Scanner: code-review/convention | * **[medium] Inconsistent async behavior between web and non-web targets**

[medium] Potential security vulnerability in JavaScript injection
The code manually escapes single quotes and backslashes for JavaScript string interpolation, but this approach is vulnerable to XSS attacks and doesn't properly escape all special characters. The current implementation could be exploited if the copied text contains malicious content.
Suggested fix: Use a proper escaping mechanism or consider using the Clipboard API directly through web_sys instead of injecting raw JavaScript strings.
*Scanner: code-review/convention | *
[medium] Potential security vulnerability in JavaScript string escaping
The JavaScript string escaping logic only handles backslash, single quote, newline, and carriage return characters. However, it doesn't escape other potentially dangerous characters like double quotes or control characters that could break out of the JavaScript string context when used in certain contexts, potentially leading to XSS vulnerabilities.
Suggested fix: Use a more comprehensive escaping mechanism or a dedicated JavaScript escaping library to properly escape all special characters that could break out of JavaScript string literals.
