# CVE-2023-29234: Bypass serialize checks in Apache Dubbo

**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. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 7.4% , percentile 94: FIRST’s model estimates a 7.4% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). 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.apache.dubbo:dubbo (Maven) >= 3.1.0, < 3.1.11, fixed in 3.1.11 ; org.apache.dubbo:dubbo (Maven) >= 3.2.0, < 3.2.5, fixed in 3.2.5 . Check your lockfile, including transitive dependencies.
