49548	PHP Uncaught errors in ID3/module.audio.ace.php	dxladner		"So this is the first time reporting a possible bug or security issue. I use the Search box to search for this possible issue and return nothing. So I am entering what information I have here:

So I am getting this error: Uncaught Error: Class 'getid3_handler' not found in /wp-includes/ID3/module.audio.ac3.php. After some reach, all I can find is it has to do with parsing audio files which we have none on our website. 

So searching all of our logs, I found this in our nginx log file:  
nginx-access.log:7732:104.198.178.229 - - [28/Feb/2020:07:20:33 +0000]  ""GET //wp-includes/ID3/module.audio.ac3.php HTTP/1.1"" 301 189 ""-"" ""python-requests/2.23.0"" 0.000 ""20.188.45.25""
nginx-access.log:7733:35.225.194.20 - - [28/Feb/2020:07:20:33 +0000]  ""GET //wp-includes/ID3/module.audio.ac3.php HTTP/1.1"" 500 5 ""-"" ""python-requests/2.23.0"" 0.166 ""20.188.45.25, 20.188.45.25""

so my thought is web-bot keeps trying to access this file for some reason. I have blocked this IP address. 
But I did not know if this could be a possible bug or security issue, as this IP which is on the IP Abuse list:  https://www.abuseipdb.com/check/20.188.45.25  keeps trying to access this file.  

Again if this is a bug, it might be causing issues with other sites using audio files OR security issue: as why would that IP address specifically target that specific file? "	defect (bug)	closed	normal		Media		normal	duplicate
