============ |
|
|
|
|
|
|
|
Synapse 0.15.0 introduces an experimental new API for previewing URLs at |
|
|
|
/_matrix/media/r0/preview_url. This is disabled by default. To turn it on |
|
|
|
you must enable the `url_preview_enabled: True` config parameter and explicitly |
|
|
|
specify the IP ranges that Synapse is not allowed to spider for previewing in |
|
|
|
the `url_preview_ip_range_blacklist` configuration parameter. This is critical |
|
|
|
from a security perspective to stop arbitrary Matrix users spidering 'internal' |
|
|
|
URLs on your network. At the very least we recommend that your loopback and |
|
|
|
RFC1918 IP addresses are blacklisted. |
