1. Vulnerability Description

• filter(.isEmpty scans the entire collection, which is likely to slow performance.

2. Vulnerability Countermeasure

• If you change it to !exists(), it is more advantageous for performance.

3. Sample Code

• Vulnerable Code

seq.filter(p).isDefined
seq.find(p).isDefined

seq.filter(p).isEmpty
seq.find(p).isEmpty

• Safe Code

seq.exists(p)
!seq.exists(p)
