{"id":"CVE-2019-19850","details":"An issue was discovered in TYPO3 before 8.7.30, 9.x before 9.5.12, and 10.x before 10.2.2. Because escaping of user-submitted content is mishandled, the class QueryGenerator is vulnerable to SQL injection. Exploitation requires having the system extension ext:lowlevel installed, and a valid backend user who has administrator privileges.","aliases":["GHSA-59pj-7mjh-4465"],"modified":"2026-08-27T08:15:24.040870Z","published":"2019-12-17T17:15:18.067Z","references":[{"type":"ADVISORY","url":"https://review.typo3.org/q/%2522Resolves:+%252389452%2522+topic:security"},{"type":"ADVISORY","url":"https://typo3.org/security/advisory/typo3-core-sa-2019-025/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/TYPO3/typo3","events":[{"introduced":"a9a68ed6a41c86e6d46629c15ca4bdffe85344f1"},{"fixed":"23b71bb1059d1a1b1ddbc49caedb5ff1c14e00f3"},{"introduced":"41235ff8e38c6f3401df03ae8beddd62d662c525"},{"fixed":"efd84a5a507792083f9f4ec03f8c7d580adfc3d8"},{"introduced":"c91b70e450c52d29ffb08115fffbb7832b15a330"},{"fixed":"b7d2c8f95222abade62827244327367995345891"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.7.30"},{"introduced":"9.0.0"},{"fixed":"9.5.12"},{"introduced":"10.0.0"},{"fixed":"10.2.2"}]}}],"versions":["v10.2.1","v10.2.0","v8.7.29","TYPO3_8-7-29","8.7.29","v9.5.11","v9.5.10","v8.7.28","TYPO3_8-7-28","8.7.28","v10.1.0","v9.5.9","v10.0.0","v9.5.8","v8.7.27","TYPO3_8-7-27","8.7.27","v8.7.26","TYPO3_8-7-26","8.7.26","v9.5.7","v8.7.25","TYPO3_8-7-25","8.7.25","v9.5.6","v9.5.5","v8.7.24","TYPO3_8-7-24","8.7.24","v9.5.4","v8.7.23","TYPO3_8-7-23","8.7.23","v8.7.22","TYPO3_8-7-22","8.7.22","v9.5.3","v9.5.2","v8.7.21","TYPO3_8-7-21","8.7.21","v9.5.1","v8.7.20","TYPO3_8-7-20","8.7.20","v9.5.0","v9.4.0","v8.7.19","TYPO3_8-7-19","8.7.19","v8.7.18","TYPO3_8-7-18","8.7.18","v8.7.17","TYPO3_8-7-17","8.7.17","v9.3.0","v8.7.16","TYPO3_8-7-16","8.7.16","v8.7.15","TYPO3_8-7-15","8.7.15","v8.7.14","TYPO3_8-7-14","8.7.14","v9.2.0","v8.7.13","TYPO3_8-7-13","8.7.13","v8.7.12","TYPO3_8-7-12","8.7.12","v8.7.11","TYPO3_8-7-11","8.7.11","v8.7.10","TYPO3_8-7-10","8.7.10","v9.1.0","v9.0.0","v8.7.9","TYPO3_8-7-9","8.7.9","v8.7.8","TYPO3_8-7-8","8.7.8","v8.7.7","TYPO3_8-7-7","8.7.7","v8.7.6","TYPO3_8-7-6","8.7.6","v8.7.5","TYPO3_8-7-5","8.7.5","v8.7.4","TYPO3_8-7-4","8.7.4","TYPO3_8-7-2","8.7.2","TYPO3_8-7-1","8.7.1","TYPO3_8-7-0","8.7.0","TYPO3_8-6-0","8.6.0","TYPO3_8-5-0","8.5.0","TYPO3_8-4-0","8.4.0","TYPO3_8-3-0","8.3.0","TYPO3_8-2-0","8.2.0","TYPO3_8-1-0","8.1.0","TYPO3_8-0-0","8.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-19850.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/typo3/typo3","events":[{"introduced":"a9a68ed6a41c86e6d46629c15ca4bdffe85344f1"},{"fixed":"23b71bb1059d1a1b1ddbc49caedb5ff1c14e00f3"},{"introduced":"41235ff8e38c6f3401df03ae8beddd62d662c525"},{"fixed":"efd84a5a507792083f9f4ec03f8c7d580adfc3d8"},{"introduced":"c91b70e450c52d29ffb08115fffbb7832b15a330"},{"fixed":"b7d2c8f95222abade62827244327367995345891"}],"database_specific":{"cpe":"cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.7.30"},{"introduced":"9.0.0"},{"fixed":"9.5.12"},{"introduced":"10.0.0"},{"fixed":"10.2.2"}],"source":"CPE_RANGE"}}],"versions":["v10.2.1","v10.2.0","v8.7.29","TYPO3_8-7-29","8.7.29","v9.5.11","v9.5.10","v8.7.28","TYPO3_8-7-28","8.7.28","v10.1.0","v9.5.9","v10.0.0","v9.5.8","v8.7.27","TYPO3_8-7-27","8.7.27","v8.7.26","TYPO3_8-7-26","8.7.26","v9.5.7","v8.7.25","TYPO3_8-7-25","8.7.25","v9.5.6","v9.5.5","v8.7.24","TYPO3_8-7-24","8.7.24","v9.5.4","v8.7.23","TYPO3_8-7-23","8.7.23","v8.7.22","TYPO3_8-7-22","8.7.22","v9.5.3","v9.5.2","v8.7.21","TYPO3_8-7-21","8.7.21","v9.5.1","v8.7.20","TYPO3_8-7-20","8.7.20","v9.5.0","v9.4.0","v8.7.19","TYPO3_8-7-19","8.7.19","v8.7.18","TYPO3_8-7-18","8.7.18","v8.7.17","TYPO3_8-7-17","8.7.17","v9.3.0","v8.7.16","TYPO3_8-7-16","8.7.16","v8.7.15","TYPO3_8-7-15","8.7.15","v8.7.14","TYPO3_8-7-14","8.7.14","v9.2.0","v8.7.13","TYPO3_8-7-13","8.7.13","v8.7.12","TYPO3_8-7-12","8.7.12","v8.7.11","TYPO3_8-7-11","8.7.11","v8.7.10","TYPO3_8-7-10","8.7.10","v9.1.0","v9.0.0","v8.7.9","TYPO3_8-7-9","8.7.9","v8.7.8","TYPO3_8-7-8","8.7.8","v8.7.7","TYPO3_8-7-7","8.7.7","v8.7.6","TYPO3_8-7-6","8.7.6","v8.7.5","TYPO3_8-7-5","8.7.5","v8.7.4","TYPO3_8-7-4","8.7.4","TYPO3_8-7-2","8.7.2","TYPO3_8-7-1","8.7.1","TYPO3_8-7-0","8.7.0","TYPO3_8-6-0","8.6.0","TYPO3_8-5-0","8.5.0","TYPO3_8-4-0","8.4.0","TYPO3_8-3-0","8.3.0","TYPO3_8-2-0","8.2.0","TYPO3_8-1-0","8.1.0","TYPO3_8-0-0","8.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-19850.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
