ثغرة أمنية في مكوّن برمجي — CVE-2026-7768

تؤثر هذه الثغرة الموثقة في fastify fastify\/accepts-serializer. يوضح سجل NVD أن المشكلة تتمثل في: @fastify/accepts-serializer cached serializer-selection results keyed by the request Accept header without a size limit or eviction policy. A remote unauthenticated client could send many distinct but matching Accept header variants to make the cache grow unbounded, eventually exhausting the Node.js heap and crashing the process. Versions <= 6.0.3 are affected. Update to 6.0.4 or later, which bounds the cache via an LRU with a default size of 100 entries, configurable through the new cacheSize plugin option.
