As published by the source; long descriptions are shortened.

The GHSA-48qw-824m-86pr hardening added a checkPermissionsOnDatabase(UPDATESECURITY) gate on the polyglot engine (PolyglotQueryEngine.java:112-114,126,176,199), but only there. The SQL route to JavaScript never touches it: DefineFunctionStatement.executeSimple (DefineFunctionStatement.java:37-100), LocalSchema.registerFunctionLibrary, and SQLQueryEngine library-function invocation (SQLQueryEngine.java:198-224) do no scripting-permission check. Exploit: any user authorized for the DB (including a read-only role) runs POST /api/v1/command/<db {"language":"sql","command":"DEFINE FUNCTION x.run \"<js\" LANGUAGE js"} then SELECT x.run(), executing arbitrary JavaScript and defeating the control meant to restrict scripting to security admins. On this path allowedPackages is empty so Java.type host lookup and reflection are blocked, but IOAccess.ALL still permits load(url) SSRF/remote-JS inclusion and unbounded CPU/memory DoS. Fix: gate DefineFunctionStatement.executeSimple, the…

# Patch Next advisory brief: GHSA-vwjc-v7x7-cm6g

Advisory: ArcadeDB: Scripting authorization gate (GHSA-48qw-824m-86pr) bypassed via SQL DEFINE FUNCTION ... LANGUAGE js
IDs: GHSA-vwjc-v7x7-cm6g
Record: https://patchnext.com/advisories/ghsa-vwjc-v7x7-cm6g (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.arcadedb:arcadedb-engine 26.7.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.arcadedb:arcadedb-engine: affected < 26.7.2; fixed in 26.7.2

## Suggested inspection (read-only)
- Maven com.arcadedb:arcadedb-engine: check the installed version with your package manager.

## 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 com.arcadedb:arcadedb-engine.
- 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://github.com/advisories/GHSA-vwjc-v7x7-cm6g (GitHub-reviewed advisory GHSA-vwjc-v7x7-cm6g lists affected ranges: Maven com.arcadedb:arcadedb-engine >=0 <26.7.2)
