TL;DR

RSC cache-busting values can collide in practical deployment conditions that use shared caches. Collisions let attackers poison cache variants so users receive incorrect component responses for a URL. The weakness is insufficient collision resistance in response variant separation. The fix strengthens cache-busting generation to reduce practical collisions and improve variant isolation.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
