GHSA-x9f9-r4m8-9xc2
GHSA-x9f9-r4m8-9xc2 is a Code Injection vulnerability in com.arcadedb:arcadedb-engine. O3 Security confirms whether GHSA-x9f9-r4m8-9xc2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
ScriptTriggerExecutor sets allowedPackages to java.lang., java.util., java.time., java.math. (ScriptTriggerExecutor.java:56); trigger creation is gated only at UPDATE_SCHEMA (LocalSchema.createTrigger:636). Permitting java.lang.* host-class lookup lets a trigger script do Java.type("java.lang.Runtime").getRuntime().exec(...) (or ProcessBuilder). The reflection denylist does not block Java.type host lookups, and allowCreateProcess(false) only restricts GraalVM's guest process API, not a host Runtime.exec reached through HostAccess.ALL.
Exploit: a user with UPDATE_SCHEMA (schema admin, strictly less than security admin) runs CREATE TRIGGER ... EXECUTE JAVASCRIPT '<runtime.exec>' and obtains OS RCE when the trigger fires.
Fix: remove java.lang.* (and narrow the rest) from the trigger allow-list; if host interop is needed, expose an explicit @HostAccess.Export API surface instead of whole packages; consider gating trigger creation at UPDATE_SECURITY. Prefer an allow-list (HostAccess.EXPLICIT) over the current denylist-over-HostAccess.ALL.
Related medium/low items to fold into the fix: IMPORT DATABASE SSRF via unfollowed-redirect re-validation (SourceDiscovery.java:113), BACKUP/EXPORT DATABASE missing authorization (BackupDatabaseStatement.java:56, ExportDatabaseStatement.java:52), chunked-transfer body-size DoS bypass (HttpServer.java:301,318-333), and no brute-force lockout on password auth (ServerSecurity.java:189-205).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.arcadedb:arcadedb-engine. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update com.arcadedb:arcadedb-engine to 26.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x9f9-r4m8-9xc2 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-x9f9-r4m8-9xc2 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-x9f9-r4m8-9xc2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
