## Overview

Crawl4AI before 0.9.5 contains an improper certificate validation vulnerability that allows network attackers to intercept crawls because Chromium always launches with --ignore-certificate-errors. Man-in-the-middle or DNS-controlling attackers can serve forged content to the crawler and read cookies and headers sent, while hard-coded --no-sandbox also overrides CRAWL4AI_CHROMIUM_SANDBOX.

## Affected

- `crawl4ai < 0.9.5`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
