Unclear The finding does not say what user-visible behavior, if any, this affects.

What

A session-memory function that previously called replaceSessionCache now instead acquires a lock via .acquire(), with a paired function releasing it via .release() at the appropriate point.

Why

Using an explicit lock instead of a cache-replace call helps prevent race conditions around session memory, making concurrent access to session state safer.
