Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-40899 in the wild and no public exploit code.\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-2026-40899/ (Markdown: https://insights.sbomify.com/CVE-2026-40899/index.md)","id":"CVE-2026-40899","markdown":"https://insights.sbomify.com/CVE-2026-40899/index.md","name":"CVE-2026-40899","record":{"aliases":["GHSA-944x-93jf-h3rx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"DataEase analytics platform","requires_auth":"low_privilege","summary":"An authenticated attacker can bypass JDBC blocklists to read arbitrary files from the server filesystem via a rogue MySQL connection.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"dataease","vendor":"dataease"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-183","name":"Permissive List of Allowed Inputs"}],"description":"DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a JDBC parameter blocklist bypass vulnerability in the MySQL datasource configuration. The Mysql class uses Lombok's @Data annotation, which auto-generates a public setter for the illegalParameters field that contains the JDBC security blocklist. When a datasource configuration is submitted as JSON, Jackson deserialization calls setIllegalParameters with an attacker-supplied empty list, replacing the blocklist before getJdbc() validation runs. This allows an authenticated attacker to include dangerous JDBC parameters such as allowLoadLocalInfile=true, and by pointing the datasource at a rogue MySQL server, exploit the LOAD DATA LOCAL INFILE protocol feature to read arbitrary files from the DataEase server filesystem, including sensitive environment variables and database credentials. This issue has been fixed in version 2.10.21.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"DataEase has an Arbitrary File Read Vulnerability","id":"CVE-2026-40899","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dataease:dataease","products":["dataease:dataease"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"DataEase has SQL Injection via Stacked Queries","id":"CVE-2026-40900"},"packages":[],"prev":{"headline":"quic-go: HTTP/3 QPACK Trailer Expansion Memory Exhaustion","id":"CVE-2026-40898"},"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-18","vendors":["dataease"]},"summary":"An authenticated attacker can bypass JDBC blocklists to read arbitrary files from the server filesystem via a rogue MySQL connection.","url":"https://insights.sbomify.com/CVE-2026-40899/"}
