FKIE_CVE-2022-39241

Vulnerability from fkie_nvd - Published: 2022-11-02 17:15 - Updated: 2026-06-17 04:57
Severity
7.6 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N
4.9 (Medium) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
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.
