Sonarr compromised by pr0n - D1ld0 Ball Super

Sonarr: 2.0.0.5283
Mono: Mono JIT compiler version 5.16.0.179
OS: Ubuntu 16.04.5 LTS (Xenial Xerus)
Description of issue: Odd ‘adult’ text replacing series title.

Wondering if anyone has seen this before. I managed to take these screen shots. Then I ran all sorts of malware/spyware in addition to the AV I already have installed and rebooted. Since then I have not been able to reproduce… Still, how concerned should I be?? Has ANYONE seen anything similar?

Tried to add a series today… Searched by TVDB ID… It yielded this search result
TVDB%20Title

Search for the same series… by Series Title, … Returned the correct name …
dbs_fullname

…but, after adding both, they displayed this in the Sonarr Library
