[Plugin: Yet Another Related Posts Plugin] A YARPP bug/exploit?

I found a visit to my blog (which has YARPP installed) that visited a page labeled “function.call-user-func-array”. This apparently set off YARPP to cause it to completely malfunction and also stop my blog from functioning entirely.

I’m almost afraid to test it thoroughly, although disabling the YARPP plugin did resolve the issue and doing a reinstallation allowed me to reactivate it without the issue. That, and blocking the malicious IP was satisfying.

Is this something that you are aware of? And is there a way to prevent it?
