There was a problem hiding this comment.
❌ Codacy found a critical Error Prone issue: Unsafe member access .target on an any value.
The issue identified by ESLint is related to the type safety of the event object in the handleInputChange function. Specifically, the linter warns that accessing the .target property on an any type is unsafe because TypeScript cannot guarantee that the event object indeed has a target property. This can lead to potential runtime errors if the assumption is incorrect.
To fix this issue, you should ensure that the event object is properly typed. In this case, the event is a React.ChangeEvent<HTMLInputElement>, which is already specified in the function signature. However, to ensure that TypeScript can infer the type correctly, you can explicitly cast the event parameter.
Here's the code suggestion to fix the issue:
| setInput(event.target.value); | |
| const handleInputChange = (event: React.ChangeEvent<HTMLInputElement>) => { |
This will ensure that TypeScript correctly understands the type of event and that accessing event.target.value is safe.

❌ Codacy found a critical Error Prone issue: 'a' is assigned a value but never used.
The issue here is that the variable a is declared and assigned a string value but is never used in the code. This is considered an error-prone practice because it introduces unnecessary code that can confuse readers and potentially lead to maintenance issues.
To fix this issue, you can simply remove the unused variable a.

dangerouslySetInnerHTML which may lead to Cross Site Scripting (XSS). By default, React components will encode the data properly before rendering.
The issue described by the Semgrep linter is a potential Cross Site Scripting (XSS) vulnerability. Using dangerouslySetInnerHTML in React can expose the application to XSS attacks if the content being rendered is not properly sanitized. This can allow attackers to inject malicious scripts that can execute in the context of the user's browser.
To fix this issue, we should avoid using dangerouslySetInnerHTML and instead render the data safely. If the data contains HTML that needs to be rendered, it should be sanitized before being used.
Here's the code suggestion to fix the issue:
| <p dangerouslySetInnerHTML={{ __html: data ? data : 'Loading data...' }}></p> {/* Vulnerable to XSS */} | |
| <p>{data ? data : 'Loading data...'}</p> |
This change removes the use of dangerouslySetInnerHTML and ensures that the content is rendered as plain text, preventing potential XSS attacks.

❌ Codacy found a critical Error Prone issue: 'a' is assigned a value but never used.
The issue identified by ESLint is that the variable a is declared and assigned a value, but it is never used in the code. This results in unnecessary code that can be removed to improve readability and maintainability.
To fix this issue, you should remove the line where the variable a is declared and assigned.

❌ Codacy found a critical Error Prone issue: Unsafe argument of type any assigned to a parameter of type SetStateAction<string>.
The issue described by ESLint indicates that the event.target.value is being assigned to the setInput function, which expects a SetStateAction<string> type. The event.target.value is of type any, which can potentially lead to type safety issues, as it can hold values of any type, not just strings.
To fix this issue, you should explicitly cast event.target.value to a string. This ensures that the value being assigned to setInput is of the expected type.
Here's the code suggestion to fix the issue:
| setInput(event.target.value); | |
| setInput(event.target.value as string); |

❌ Codacy found a critical Error Prone issue: Unsafe argument of type any assigned to a parameter of type string.
The issue identified by ESLint is that the variable someProp is of type any, which means it could potentially hold any type of value, including types that could lead to vulnerabilities like Cross-Site Scripting (XSS) if not properly sanitized. By assigning it directly to a parameter of type string, you risk passing unsafe values into the fetchData function.
To fix this issue, you should ensure that someProp is explicitly typed as string. This will enforce type safety and help prevent potential vulnerabilities.
Here is the code suggestion to fix the issue:
| fetchData(someProp); | |
| fetchData(someProp as string); |

There was a problem hiding this comment.
The issue identified by ESLint is that the dangerouslySetInnerHTML prop is being used with unencoded input, which can lead to Cross-Site Scripting (XSS) vulnerabilities. XSS attacks occur when malicious scripts are injected into web pages viewed by other users. In this case, if data contains any malicious scripts, they will be executed in the user's browser.
To fix this issue, you should avoid using dangerouslySetInnerHTML unless absolutely necessary. Instead, you can render the text content directly. Here's the code suggestion to fix the issue:
| <p dangerouslySetInnerHTML={{ __html: data ? data : 'Loading data...' }}></p> {/* Vulnerable to XSS */} | |
| <p>{data ? data : 'Loading data...'}</p> |
This change ensures that the content is rendered as plain text, which mitigates the risk of XSS attacks.
