Discourse's SSRF protection missing for some FastImage requests
Summary
Discourse's SSRF protection missing for some FastImage requests
Original description
The description as published by the source.
Discourse is an open-source discussion platform. Prior to version 3.1.0, some user provided URLs were being passed to FastImage without SSRF protection. Insufficient protections could enable attackers to trigger outbound network connections from the Discourse server to private IP addresses. This affects any site running the version 3.1.0 and prior. This issue is patched in version 3.1.0. There are no known workarounds.
