How severe is GHSA-x9f9-r4m8-9xc2?

No CVSS score has been assigned to GHSA-x9f9-r4m8-9xc2 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-x9f9-r4m8-9xc2?

GHSA-x9f9-r4m8-9xc2 affects the following packages: com.arcadedb:arcadedb-engine (Maven). Ecosystems affected: Maven.

How do I fix GHSA-x9f9-r4m8-9xc2?

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.

How do I detect GHSA-x9f9-r4m8-9xc2 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.arcadedb:arcadedb-engine, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-x9f9-r4m8-9xc2 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is GHSA-x9f9-r4m8-9xc2 actively exploited in the wild?

No public exploit code has been indexed for GHSA-x9f9-r4m8-9xc2 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-x9f9-r4m8-9xc2?

GHSA-x9f9-r4m8-9xc2 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 60th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-x9f9-r4m8-9xc2?

GHSA-x9f9-r4m8-9xc2 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-x9f9-r4m8-9xc2 published, and has it been updated?

GHSA-x9f9-r4m8-9xc2 was published on July 16, 2026 and was last updated on August 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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).
