What is CVE-2025-2888?

A vulnerability in Tough, a library developed by AWS, arises when the client improperly caches timestamp metadata during a snapshot rollback. This caching issue leads to failed update timestamp validation, effectively halting subsequent updates until the cache is manually cleared. To mitigate this risk, users are strongly advised to upgrade to Tough version 0.20.0 or later, ensuring any forked or derivative code is also patched to implement the necessary fixes.
