Good afternoon.
Since the bug also impacts Mozilla Firefox and Mozilla Thunderbird, could you add the following cpe?
mozilla:firefox
mozilla:thunderbird
https://www.mozilla.org/en-US/security/advisories/mfsa2024-21/
We would appreciate it very much.
Best Regards,

It appears to be very odd that Mozilla assigned Firefox and Thunderbird as primary products in the CVE because PDF.js is an independent product. We have created dedicated entries: VDB-265784 and VDB-265785
