{"id":"CVE-2026-33121","summary":"DataEase has SQL Injection via Datasource Save Flow","details":"DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a SQL injection vulnerability in the API datasource saving process. The deTableName field from the Base64-encoded datasource configuration is used to construct a DDL statement via simple string replacement without any sanitization or escaping of the table name. An authenticated attacker can inject arbitrary SQL commands by crafting a deTableName that breaks out of identifier quoting, enabling error-based SQL injection that can extract database information such as the MySQL version. This issue has been fixed in version 2.10.21.","aliases":["GHSA-fg4m-q7ch-jqv5"],"modified":"2026-07-15T01:49:21.608929334Z","published":"2026-04-16T18:16:02.485Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33121.json"},"references":[{"type":"WEB","url":"https://github.com/dataease/dataease/releases/tag/v2.10.21"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33121.json"},{"type":"ADVISORY","url":"https://github.com/dataease/dataease/security/advisories/GHSA-fg4m-q7ch-jqv5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33121"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dataease/dataease","events":[{"introduced":"0"},{"fixed":"e1085ffb75f42b6aca117edf36b30276bfdfe9aa"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:dataease:dataease:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.10.21"}]}}],"versions":["v2.10.20","v2.10.19","v2.10.18","v2.10.17","v2.10.16","v2.10.15","v2.10.14","v2.10.13","v2.10.12","v2.10.11","v2.10.10","v2.10.9","v2.10.8","v2.10.7","v2.10.6","v2.10.5","v2.10.4","v2.10.3","v2.10.2","v2.10.1","v2.10.0","v2.6.0","v2.3.0","v2.2.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33121.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
