Brian replied with this:
"
If I had to
take a guess, libcurl is
dumping the response from DPM to stdout, stdout is being picked
up by systemd, and systemd is forwarding this to syslog. I
would open a ticket with XRootD (should be a simple fix) but you
can probably override the systemd unit so the logs don't get
forwarded in that way.
"
I am not sure how to override the systemd unit.

Hmmh, I don't think cmssw has much to do with this, either :)
If it's in syslog from a running xrootd it is probably coming from some plugin.
I remember lcmaps used to put auth errors into syslog.
I'd guess it has something to do with tokens -- as it reports Created resource
... file-name ... token=xyzz.

Hi Bockjoo,
This appears to have nothing to do with xrootd but cmssw, instead. Please
contact the cmssw developers.

In the syslog, there are the html messages that trigger some security alert.
The messages look like:
