Answer in brief
CVE-2026-19826 records a Unknown severity vulnerability in alldatacenter alldata xxl-rpc Listener HessianSerializer.java Hessian2Input.readObject deserialization. The current sources do not mark it as known exploited. The current feed maps alldatacenter/alldata (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A vulnerability was detected in alldatacenter alldata up to 0.6.8. This affects the function Hessian2Input.readObject of the file /serialize/impl/HessianSerializer.java of the component xxl-rpc Listener. The manipulation results in deserialization. The attack may be performed from remote. The exploit is now public and may be used. The project closed the issue report as "not planned" without any further explanation.
