Systems that use in-memory cache backends like redis / memcache
are more likely to be affected by this issue. This is due the
common strategy used to free cache space if the configured
memory limit of the cache is reached.

It is not clear and can't be assumed, because it doesn't explain
what 'common strategy' is assumed here?

As of 2.4.2, BOA doesn't even use Redis new default (noeviction).
We use 'volatile-lru' (like before) with 'maxmemory-samples 5',
as shown here:

But does it translate to 'more likely to be affected'?
What the 'more likely' exactly means in this context?
No idea.

Why not to just upgrade and forget?
