{"id":"GHSA-2c5x-4jgf-88mj","summary":"NocoDB: SSRF Protection Bypass in Notification Webhook Plugins (Slack, Discord, Mattermost, Teams)","details":"### Summary\n\nThe `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.\n\n### Details\n\n`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:\n\n```ts\n// packages/nocodb/src/plugins/slack/Slack.ts (and Discord / Mattermost / Teams — identical pattern)\nreturn await axios.post(webhook_url, {\n  text,\n  httpAgent: useAgent(webhook_url),   // wrong position — serialised, not used\n  httpsAgent: useAgent(webhook_url),\n});\n```\n\nThe 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.\n\nThis is distinct from GHSA-xr7v-j379-34v9, which covers a blind SSRF via HEAD in the upload-by-URL path.\n\n### Impact\n\n- Authenticated user (Editor+) can reach cloud-metadata endpoints (`169.254.169.254`) and internal services.\n- Combined with verbose hook logging (`NC_AUTOMATION_LOG_LEVEL=ALL`), response bodies may be exfiltrated.\n\n### Credit\n\nThis issue was reported by [@ik0z](https://github.com/ik0z).","aliases":["CVE-2026-46548"],"modified":"2026-07-20T21:30:36.150392583Z","published":"2026-05-21T20:34:28Z","database_specific":{"nvd_published_at":"2026-06-23T21:16:58Z","cwe_ids":["CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-05-21T20:34:28Z"},"references":[{"type":"WEB","url":"https://github.com/nocodb/nocodb/security/advisories/GHSA-2c5x-4jgf-88mj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46548"},{"type":"PACKAGE","url":"https://github.com/nocodb/nocodb"}],"affected":[{"package":{"name":"nocodb","ecosystem":"npm","purl":"pkg:npm/nocodb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.301.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-2c5x-4jgf-88mj/GHSA-2c5x-4jgf-88mj.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
