ecosystem impact- 17 maven packages depend on com.arcadedb:arcadedb-engine (8 direct, 9 indirect)
Ecosystem-wide dependent count for version 26.7.2.
DescriptionCVE.org
ArcadeDB before 26.7.2 (arcadedb-engine) allows trigger scripts to look up host classes in java.lang.* (via Java.type) because ScriptTriggerExecutor adds java.lang.* to the allowed packages. An authenticated user with UPDATE_SCHEMA permission can create a JavaScript trigger that invokes java.lang.Runtime.getRuntime().exec() (or ProcessBuilder), achieving OS command execution when the trigger fires.
AnalysisAI
OS command execution in ArcadeDB (arcadedb-engine) before 26.7.2 lets an authenticated user with UPDATE_SCHEMA permission escalate to full remote code execution on the host. Because ScriptTriggerExecutor whitelists java.lang.* for JavaScript trigger scripts, an attacker can create a trigger that calls Java.type("java.lang.Runtime").getRuntime().exec() (or ProcessBuilder) and runs arbitrary OS commands when the trigger fires. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated ArcadeDB account holding the UPDATE_SCHEMA (schema-admin) permission - the exact privilege gate at LocalSchema.createTrigger:636 - which is strictly less than the security-admin role. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H, score 9.3) rates this unauthenticated, but the CVE description and GHSA advisory both state exploitation requires an authenticated user holding UPDATE_SCHEMA permission - a direct conflict. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained (or been granted) a database account with UPDATE_SCHEMA permission issues CREATE TRIGGER ... EXECUTE JAVASCRIPT with a body that calls Java.type("java.lang.Runtime").getRuntime().exec(). … |
| Remediation | Vendor-released patch: 26.7.2 - upgrade arcadedb-engine (com.arcadedb:arcadedb-engine) to 26.7.2 or later, per GHSA-x9f9-r4m8-9xc2. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all ArcadeDB deployments running versions prior to 26.7.2 and immediately restrict UPDATE_SCHEMA permissions to essential administrative accounts only. …
