Intruders have automated web crawlers that can scan your site for known security vulnerabilities. When the web crawler detects a vulnerability, it alerts the intruder. From there, the intruder just needs to figure out how to exploit the vulnerability on your site.
Stop using each of the libraries that Lighthouse flags. If the library has released a newer version that fixes the vulnerability, upgrade to that version, or consider using a different library.
See Snyk's Vulnerability DB to learn more about each library's vulnerability.
To detect vulnerable libraries, Lighthouse:
- Runs Library Detector For Chrome.
- Checks the list of detected libraries against Snyk's Vulnerability DB.
An intruder can scan your entire site using the process above and a web crawler.
