Summary

Crawl4AI from unclecode before 0.9.5 always launches Chromium with certificate errors ignored, an improper certificate validation flaw (CWE-295). A man-in-the-middle or DNS-controlling network attacker can serve forged content to the crawler and read the cookies and headers it sends.

Description from the CNA

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.
