What most tools give you

Typical output

Rule: js.security.audit.detect-non-literal-regexp
Severity: WARNING

Message:
RegExp() called with a $ARG function argument. This may allow an attacker to trigger a Regular Expression Denial of Service (ReDoS), as regex evaluation can block the main thread.

If user-controlled input is used, this can lead to application slowdown or unresponsiveness. It is recommended to avoid dynamic regex construction or ensure that inputs are properly validated.

Consider using safe, pre-defined patterns, or a validation/sanitization library to mitigate potential ReDoS vulnerabilities.

What you actually need

Plain-English explanation

Problem: User input is used inside a regex.

Why it matters: An attacker could cause your app to hang or crash.

What to do: Validate or sanitize the input before using it in RegExp.

Fix prompt (copy/paste)

You are a senior security engineer. Fix this issue safely.

Issue: Detect Non Literal Regexp (ReDoS risk)
File: src/lib/highlightText.tsx (line 25)

Current code:
const re = new RegExp(userInput, "i");

Goal:
Prevent user-controlled input from creating a dynamic RegExp.

Fix:
- Do NOT pass raw user input into new RegExp().
- Replace with one of:
  A) Escape userInput so it becomes a literal match, OR
  B) Use a safe allowlist of patterns, OR
  C) Avoid RegExp entirely (e.g., string includes) if possible.
- Keep existing behavior and add/adjust tests if needed.

Return:
1) The updated code (minimal diff)
2) A brief explanation of why this is safer
