| Summary | NocoDB: SSRF Protection Bypass in Notification Webhook Plugins (Slack, Discord, Mattermost, Teams) ### Summary 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. ### Details `axios.post(url, data, config)` expects connection agents in the third (config) argument. In all four plugins, the agents were placed in the second (data) argument and serialised as JSON body content: ```ts // packages/nocodb/src/plugins/slack/Slack.ts (and Discord / Mattermost / Teams — identical pattern) return await axios.post(webhook_url, { text, httpAgent: useAgent(webhook_url), // wrong position — serialised, not used httpsAgent: useAgent(webhook_url), }); ``` The webhook flow: an Editor+ user creates a webhook with `notification.payload.channels[].webhook_url` pointing to an internal host; on trigger, `WebhookInvoker.invoke()` calls the plugin's `sendMessage()` which performs the outbound `axios.post` with no SSRF filtering applied. This is distinct from GHSA-xr7v-j379-34v9, which covers a blind SSRF via HEAD in the upload-by-URL path. ### Impact - Authenticated user (Editor+) can reach cloud-metadata endpoints (`169.254.169.254`) and internal services. - Combined with verbose hook logging (`NC_AUTOMATION_LOG_LEVEL=ALL`), response bodies may be exfiltrated. ### Credit This issue was reported by [@ik0z](https://github.com/ik0z). |
