CVE-2026-46548: NocoDB: SSRF Protection Bypass in Notification Webhook Plugins (Slack, Discord, Mattermost, Teams)

May 21, 2026

The request-filtering-agent SSRF protection was non-functional in the four notification webhook plugins (Slack, Discord, Mattermost, Teams) because httpAgent / httpsAgent were passed as part of the request body rather than the axios config. An authenticated user with hook-creation permission could direct outbound POST requests to arbitrary internal hosts.
