next is vulnerable to Cache Poisoning

Medium Risk
This Affects:
nextTL;DR
React Server Component request classification and cache-busting interpretation can diverge under shared-cache conditions. An attacker can cause component payload variants to be cached and served for normal URL requests. This can poison cache entries and return incorrect response formats to later users. The fix aligns header interpretation and enforces intended cache-busting behavior for RSC variants.
