Next.js versions from 16.3.0 to 16.3.7 warm `use cache` handlers using `next\/root-params` and can leak their return value to pages with different root params. With Cache Components enabled (cacheComponents: true), a ‘use cache’ function that calls another ‘use cache’ function that reads a root param can be keyed incorrectly when the inner call is served from an existing entry: the enclosing function’s cache key then omits that root param. The enclosing entry is written once and reused for all root param values, so a response for one root param value can serve content produced for a different value \u2014 whether the page is prerendered at build time or at runtime, or rendered dynamically. Shared cache headers let downstream caches redistribute the content further.<\/p>\n
What values are leaked cannot be attacker controlled. Which value’s content is served depends only on which invocation wrote the entry first.<\/p>\n
