    Published: 29 Oct 2026Last Modified: 31 Oct 2026

    Summary: Crawl4AI before 0.9.5 Improper Certificate Validation via Hard-coded Chromium Flags

    Details: 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.
