CVE-2024-13879Network attack vector

Internal service access via unsafe Slack webhook

Published Feb 17, 2025 · Updated Apr 8, 2026

SSRF in XWP Stream 4.0.2 and earlier allows remote authenticated users to send requests to arbitrary hosts through Slack alerts. The Slack alert handler passes its configured webhook URL to wp_remote_post(), which permits requests to private or reserved addresses. Administrator access and a configured Slack alert are required; resulting requests can query or modify information exposed by internal services.
