Arbitrary Code Execution via PDF JavaScript Remote Script Loading
CVE-2026-12057 is an arbitrary code execution vulnerability in a PDF application, likely associated with a Foxit product per the referenced Foxit security bulletin. The issue arises when JavaScript embedded in a PDF is executed inside the application's sandbox, but the sandbox does not properly intercept certain dangerous interfaces. Because those interfaces remain reachable, a malicious PDF can cause remote scripts to be loaded and executed, defeating the intended sandbox restrictions. The described weakness is consistent with inclusion or execution of functionality from an untrusted control sphere, enabling attacker-controlled script content to participate in the document-processing flow and ultimately leading to arbitrary code execution.
