• CVE-2026-45548: 0.26% estimated exploitation activity in the next 30 days; percentile 17.49 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Vulnerability Details CWE-918: Server-Side Request Forgery (SSRF) The processUrlFile function in packages/server/src/automations/steps/ai/extract.ts uses fetch(fileUrl) directly without the IP blacklist validation that is consistently applied to all other automation steps. This allows an authenticated user to trigger server-side requests to internal network addresses. Vulnerable Code packages/server/src/automations/steps/ai/extract.ts (lines 116, 139): Contrast with All Other Automation Steps (Same Codebase) Every other automation step that makes outbound HTTP requests properly uses fetchWithBlacklist: - steps/slack.ts:19: response = await fetchWithBlacklist(url, {...}) - steps/discord.ts:28: response = await fetchWithBlacklist(url, {...}) - steps/zapier.ts:33: response = await fetchWithBlacklist(url, {...}) - steps/n8n.ts:53: response = await fetchWithBlacklist(url, request) - steps/outgoingWebhook.ts: response = await fetchWithBlacklist(url, {...}) - steps/make.ts: response = await…

# Patch Next advisory brief: CVE-2026-45548

Advisory: Budibase: SSRF in AI Extract File Automation Step via Missing IP Blacklist Validation
IDs: CVE-2026-45548, GHSA-rpj4-7x2v-wjrf
Record: https://patchnext.com/advisories/cve-2026-45548 (revision 2, source checked 26 Oct 2026, 12:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @budibase/server 3.34.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @budibase/server: affected < 3.34.8; fixed in 3.34.8

## Suggested inspection (read-only)
- `npm ls @budibase/server --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @budibase/server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-rpj4-7x2v-wjrf (OSV record GHSA-rpj4-7x2v-wjrf lists affected ranges: npm @budibase/server >=0 <3.34.8 (fixed))
- Verified: https://github.com/advisories/GHSA-rpj4-7x2v-wjrf (GitHub-reviewed advisory GHSA-rpj4-7x2v-wjrf lists affected ranges: npm @budibase/server >=0 <3.34.8)
