nocodbnpmDescription
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:
// 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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of nocodb has shipped for CVE-2026-46548 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
