Malware in Plug-in? (php.malware.assert.004)

Hi

I upgraded the plug-in to Version 4.0.0 yesterday

We have Securi monitoring our site and I got the warning this morning

“Warning: File possibly compromised: .\wp-content\plugins\cloudflare\vendor\phpunit\phpunit\src\Framework\TestBuilder.php (php.malware.assert.004). Manual review recommended.”

False alarm?
