Resolution Note (2019.3.X):
This issue is caused by invalidated texels, which hit the back faces of the one-sided object. You can verify that by switching to Texel Validity view. To fix this, simply check Enable Double Sided Global Illumination for your one-sided material, in the material inspector.
