CVE-2026-40901
Published: 16 April 2026
Description
DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below ship the legacy velocity-1.7.jar, which pulls in commons-collections-3.2.1.jar containing the InvokerTransformer deserialization gadget chain. Quartz 2.3.2, also bundled in the application, deserializes job data BLOBs from the…

qrtz_job_details table using ObjectInputStream with no deserialization filter or class allowlist. An authenticated attacker who can write to the Quartz job table, such as through the previously described SQL injection in previewSql, can replace a scheduled job's JOB_DATA with a malicious CommonsCollections6 gadget chain payload. When the Quartz cron trigger fires, the payload is deserialized and executes arbitrary commands as root inside the container, achieving full remote code execution. This issue has been fixed in version 2.10.21.
Mitigating Controls (NIST 800-53 r5)AI
Requires timely patching of the deserialization vulnerability fixed in DataEase v2.10.21, directly eliminating the unsafe ObjectInputStream usage in Quartz.
Validates inputs to prevent SQL injection in features like previewSql, blocking authenticated attackers from writing malicious payloads to the qrtz_job_details table.
Enforces least privilege to restrict authenticated users' write access to critical Quartz job tables, mitigating the prerequisite for injecting deserialization gadgets.
Security SummaryAI
CVE-2026-40901 is a deserialization vulnerability in DataEase, an open-source data visualization and analytics platform. Versions 2.10.20 and below bundle the legacy velocity-1.7.jar, which includes commons-collections-3.2.1.jar containing the InvokerTransformer gadget chain. The bundled Quartz 2.3.2 scheduler deserializes job data BLOBs from the qrtz_job_details table using ObjectInputStream without any deserialization filter or class allowlist, enabling the CWE-502 deserialization of untrusted data. The issue carries a CVSS v3.1 score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
An authenticated attacker with write access to the Quartz job table, such as through the previously disclosed SQL injection in the previewSql feature, can replace a scheduled job's JOB_DATA field with a malicious CommonsCollections6 gadget chain payload. When the associated Quartz cron trigger fires, the payload is deserialized, resulting in arbitrary command execution as root inside the container and achieving full remote code execution.
The vulnerability has been addressed in DataEase version 2.10.21, as detailed in the project's release notes and security advisory. Security practitioners should upgrade to v2.10.21 or later and review access controls on the Quartz job tables to mitigate risks from chained exploits.
