• CVE-2026-45718: 0.15% estimated exploitation activity in the next 30 days; percentile 3.86 (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.

Summary The row action trigger endpoint (POST /api/tables/:sourceId/actions/:actionId/trigger) fails to validate that the user-supplied rowId is within the scope of the view's row filters. A user with access to a filtered view can trigger row actions on any row in the underlying table, including rows explicitly excluded by the view's security filters. Details View filters in Budibase are treated as a security boundary. The search path (packages/server/src/sdk/workspace/rows/search.ts:93-94) explicitly enforces view query filters with the comment: "that could let users find rows they should not be allowed to access." However, the row action trigger path bypasses this enforcement entirely: 1. Route (packages/server/src/api/routes/rowAction.ts:55-59): Accepts a sourceId that can be a viewId. 2. Middleware (packages/server/src/middleware/triggerRowActionAuthorised.ts:24-55): Correctly validates that the user has READ permission on the view and that the row action is enabled for that…

# Patch Next advisory brief: CVE-2026-45718

Advisory: Budibase: Row Action Trigger Bypasses View Row Filter Security Boundary Allowing Action on Out-of-Scope Rows
IDs: CVE-2026-45718, GHSA-3263-v5v9-xq8q
Record: https://patchnext.com/advisories/cve-2026-45718 (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: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: budibase 3.38.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm budibase: affected < 3.38.1; fixed in 3.38.1

## Suggested inspection (read-only)
- `npm ls budibase --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.
- 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-3263-v5v9-xq8q (OSV record GHSA-3263-v5v9-xq8q lists affected ranges: npm budibase >=0 <3.38.1 (fixed))
- Verified: https://github.com/advisories/GHSA-3263-v5v9-xq8q (GitHub-reviewed advisory GHSA-3263-v5v9-xq8q lists affected ranges: npm budibase >=0 <3.38.1)
