Wordfence advisory
medium · CVSS 6.4PDF.js is vulnerable to Arbitrary JavaScript Execution in versions prior to 4.2.67. This is due to a missing type check when handling fonts. This makes it possible for authenticated attackers, with contributor-level or above permissions, to execute arbitrary JavaScript if they can successfully trick a user into opening a crafted PDF file.

Which update should I install?

Does an affected version mean my website has been hacked?

Does a version outside these ranges mean my website is secure?
A version outside the reported ranges is not listed as affected by this particular issue. Other vulnerabilities, missing information or a previous compromise still need separate checks. Review other reports for your product and keep your website maintained.
