This issue affects Apache Lucy: all versions.

Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Because Apache Lucy is retired and no fixed version will be released, mitigate the Apache Lucy Uncontrolled Recursion (QueryParser unbounded recursion on deeply-nested query leading to C-stack overflow DoS) by restricting access to the Apache Lucy instance to trusted users only.
