Next.js vulnerable to cache poisoning via collisions in React Server Component cache-busting

發布日:2026/5/11修改日:2026/5/14

描述

### Impact React Server Component responses can be vulnerable to cache poisoning in deployments that rely on shared caches with insufficient response partitioning. In affected conditions, collisions in the `_rsc` cache-busting value can allow an attacker to poison cache entries so users receive the wrong response variant for a given URL. ### Fix We strengthened the `_rsc` cache-busting mechanism to make practical collisions significantly harder and to better separate response variants that should not share cache entries. ### Workarounds If you cannot upgrade immediately, ensure intermediary caches correctly honor `Vary` for RSC-related request headers, or disable shared caching for affected RSC responses until you can deploy a patched release.
