Hi,
we observed the same issue after upgrading to GeoServer 2.13.1.
Unfortunately we haven't found a quick fix for a running instance except
patching the underlying imageio-ext library used in GS. The patch is
available as a PR here [1].

I have recently upgraded from Geoserver 2.11.0 to 2.13.1 and have found
my external graphics for point layers are not displaying (they revert to
a default grey symbol).
Is there anything wrong in my code, or has anything changed between 2.11
and 2.13 which might be causing problems? Inaccessibility problems for
Geoserver to online resources?
An example of my xml is below:
