CVE-2025-2888

Improper timestamp caching during snapshot rollback in tough

State: Published
Severity: 5.7 Medium
Published: Mar 27, 2025
Updated: Oct 14, 2025
Reserved: Mar 27, 2025

Description

During a snapshot rollback, the client incorrectly caches the timestamp metadata. If the client checks the cache when attempting to perform the next update, the update timestamp validation will fail, preventing the next update until the cache is cleared. Users should upgrade to tough version 0.20.0 or later and ensure any forked or derivative code is patched to incorporate the new fixes.
