Weakness: CWE-918

Description

NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, 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. This vulnerability is fixed in 2026.04.1.

Affected products
