As the specified codebase does not have to match the applet's actual origin, this allowed malicious site to bypass SOP via spoofed codebase value.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
