Now produce JSON. product_name: "3 words ONLY. The specific product or service name affected." That would be "iOS and iPadOS" possibly? But description covers multiple. The primary? Since all Apple OSes, we can say "Apple OS (iOS/macOS)"? The rule: "1-3 words ONLY. The specific product or service name affected. Examples: 'Apache Tomcat', 'WordPress', 'Linux Kernel', 'nginx-ui', 'GoAnywhere MFT'. NOT the vulnerability type, NOT the vendor alone, NOT a description. If multiple products, pick the primary one." Which primary? The CVE covers all Apple OS families: iOS, iPadOS, macOS, tvOS, watchOS. Probably best to say "Apple operating systems" or "Apple iOS/macOS". But need 1-3 words. "Apple OS" might be acceptable, but that's too generic. "iOS" alone? But the vulnerability isn't iOS-specific; it's across. I'll pick "Apple iOS, macOS" – 3 words. Or "Apple OSes". I'll go with "Apple OS" (2 words). The product_name field is for the product name. Since it's a cross-platform issue in Apple's core OS, I'll label it "Apple iOS and macOS" (4 words, too l
