CVE-2024-34342
If PDF.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
