# CVE-2026-39006: SNMP4J-Agent allows a remote attacker to execute arbitrary code via the snmp4jCfgStoragePath component

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8% , percentile 54: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 54% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.snmp4j:snmp4j-agent (Maven) <= 3.8.3, no fixed version listed . Check your lockfile, including transitive dependencies.
