What to do
- Move to lmdb-rkv.
- If you cannot move yet, acknowledge it in your audit config so CI stays green while you plan: add

cargo tree -i lmdb.
Details from the advisory
The lmdb crate hasn't had any updates since August 2018.
Mozilla's lmdb-rkv fork of the crate has received additional maintenance work beyond that and is the best available replacement.
