Recommendation: Plan a near-term fix — a public PoC already exists.

FileZilla 3.40.0 contains a denial of service vulnerability in the local search functionality that allows local attackers to crash the application by supplying a malformed path string. Attackers can trigger the crash by entering a crafted path containing 384 'A' characters followed by 'BBBB' and 'CCCC' sequences in the search directory field and initiating a local search operation.
