Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-40901 exists.\n\nAffected product: Dataease Dataease. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-40901/ (Markdown: https://insights.sbomify.com/CVE-2026-40901/index.md)","id":"CVE-2026-40901","markdown":"https://insights.sbomify.com/CVE-2026-40901/index.md","name":"CVE-2026-40901","record":{"aliases":["GHSA-gm5q-g72w-c466"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DataEase analytics platform","requires_auth":"low_privilege","summary":"An authenticated attacker can achieve remote code execution by injecting malicious payloads into Quartz job data, which are deserialized without filters.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"dataease","vendor":"dataease"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-25","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-25T19:57:33Z","kind":"github_poc","ref":"https://github.com/joaovicdev/EXPLOIT-CVE-2026-40901","stars":1,"title":null}],"tier":"weaponised"},"has_fix":false,"headline":"DataEase: Quartz Deserialization → Remote Code Execution","id":"CVE-2026-40901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dataease:dataease","products":["dataease:dataease"],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"PhpSpreadsheet: CPU Denial of Service via Unbounded Row Number in XLSX Row Dimensions","id":"CVE-2026-40902"},"packages":[],"prev":{"headline":"DataEase has SQL Injection via Stacked Queries","id":"CVE-2026-40900"},"products":["dataease"],"published":"2026-04-16","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2024-57707","kev_date_added":null,"published":"2025-02-07"},{"cvss_score":9.8,"headline":"DataEase's H2 datasource has a remote command execution risk","id":"CVE-2024-46997","kev_date_added":null,"published":"2024-09-23"},{"cvss_score":9.8,"headline":"DataEase data source has deserialization vulnerability","id":"CVE-2023-33963","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":9.8,"headline":"SQL injection vulnerability due to the keyword blacklist for defending against SQL injection will be bypassed","id":"CVE-2023-28437","kev_date_added":null,"published":"2023-03-24"},{"cvss_score":9.8,"headline":"Dataease Mysql Data Source JDBC Connection Parameters Not Verified Leads to Deserialization Vulnerability","id":"CVE-2022-39312","kev_date_added":null,"published":"2022-10-25"},{"cvss_score":9.8,"headline":"Dataease before 1.11.2 allows arbitrary code execution via crafter plugin","id":"CVE-2022-34113","kev_date_added":null,"published":"2022-07-22"},{"cvss_score":9.8,"headline":"Dataease v1.11.1 SQL Injection via parameter dataSourceId","id":"CVE-2022-34115","kev_date_added":null,"published":"2022-07-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-17","vendors":["dataease"]},"summary":"An authenticated attacker can achieve remote code execution by injecting malicious payloads into Quartz job data, which are deserialized without filters.","url":"https://insights.sbomify.com/CVE-2026-40901/"}
