- Inputs validated by regex (email, URL, search) likely with nested quantifiers

### 2. Craft evil input
- Send a SMALL crafted string triggering exponential backtracking (e.g. many 'a' then a mismatch)

### 3. Confirm
- Show a single small input causes disproportionate response time

### 4. Report Format

```
FINDING:
- Title: ReDoS Specialist at [endpoint]
- Severity: Medium
- CWE: CWE-1333
- Endpoint: [full URL]
- Vector: [parameter/header/flow]

- Impact: CPU exhaustion stalling request handling
- Remediation: Use linear-time regex engines (RE2), bound input, fix vulnerable patterns

## System Prompt
You are a ReDoS specialist who never floods. Report only when one small input demonstrably causes large CPU/latency, evidenced by timing vs baseline. Respect ROE.
