Descrizione

**Description**
I am testing the CodeQL accuracy by seeding different types of XSS vulnerabilities and running the advanced workflow with security-extended and security-and-quality queries. I noticed an issue with CodeQL flagging vulnerabilities in .tsx files. While the seeded code is detected as expected in route.ts, it is not in the component files. In both cases, at least CWE-79 should be noted.

**Setup**
- GitHub Advanced Security enabled on a public test repo
- Language: typescript
- Framework: Next.js
- CodeQL initialized with codeql/javascript-queries and security-extended,security-and-quality

**Workflow file**

```
name: "CodeQL Advanced"

push:
branches: ["main", "security/*"]
pull_request:

analyze:
name: Analyze (${{ matrix.language }})
runs-on: ${{ (matrix.language == 'swift' && 'macos-latest') || 'ubuntu-latest' }}

**Expected CWEs that are not detected, but are present in documentation (https://codeql.github.com/codeql-query-help/javascript-cwe/)**
CWE-79

```tsx
export default function Seed({ msg }: { msg: string }) {
return (


Seed XSS page




);
}
```

CWE-20/CWE-116

```tsx
export async function getServerSideProps(context: GetServerSidePropsContext) {
const { query } = context;
const msg = query?.msg ?? "";
return { props: { msg } };
}
```

CWE-79

```tsx
export default function TestPage({ userInput }: TestPageProps) {
return ;
}
```

CWE-20/CWE-601

```tsx
export async function getServerSideProps(context: GetServerSidePropsContext) {
return { props: { userInput: context.query.content || "" } };
}
```

CWE-79

```tsx


```

CWE-116

```tsx
const userInput =
userContent || "Hello";
```

**Questions**
- Is there additional setup needed for scanning React?
- Why is CWE-79 and CWE-116 flagged is a .ts file and ignored in .tsx?

Direzione di ricerca

Riproduci il report con il workflow GitHub Actions mostrato, confrontando i risultati di route.ts predisposti con gli esempi di componenti .tsx. Inizia esaminando codeql/javascript-queries e le selezioni di query security-extended e security-and-quality. Il lavoro è completo quando viene spiegata la differenza di rilevamento tra TypeScript e TSX e viene identificata la modifica necessaria alla query o all’analisi, con verifica rispetto ai casi CWE-79 e CWE-116 elencati.
