CVE-2022-39241 (GCVE-0-2022-39241)

Vulnerability from cvelistv5 – Published: 2022-11-02 00:00 – Updated: 2025-04-23 16:41

Title
Possible Server-Side Request Forgery (SSRF) in webhooks
Summary
Discourse is a platform for community discussion. A malicious admin could use this vulnerability to perform port enumeration on the local host or other hosts on the internal network, as well as against hosts on the Internet. Latest `stable`, `beta`, and `test-passed` versions are now patched. As a workaround, self-hosters can use `DISCOURSE_BLOCKED_IP_BLOCKS` env var (which overrides `blocked_ip_blocks` setting) to stop webhooks from accessing private IPs.
