{"id":"CVE-2026-23921","details":"A low privilege Zabbix user with API access can exploit a blind SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL selects via the sortfield parameter. Although query results are not returned directly, an attacker can exfiltrate arbitrary database data through time-based techniques, potentially leading to session identifier disclosure and administrator account compromise.","modified":"2026-09-12T08:14:50.850247Z","published":"2026-03-24T19:16:50.563Z","database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:a:zabbix:zabbix:*:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"7.2.0"},{"fixed":"7.2.15"}],"source":"CPE_RANGE","vendor_product":"zabbix:zabbix"}]},"references":[{"type":"ADVISORY","url":"https://support.zabbix.com/browse/ZBX-27640"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zabbix/zabbix","events":[{"introduced":"49955f1fb5c9168a8a24b053f7ade6b3d903143c"},{"fixed":"ba52e2ee4ff8768c8450819a772886d79dcde0b4"},{"introduced":"372a4e93c48ecd25aa666949a055a02369031861"},{"fixed":"626d2b8a4820a424efe8fd39df3b706468f1e5d4"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:zabbix:zabbix:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"7.0.0"},{"fixed":"7.0.22"},{"introduced":"7.4.0"},{"fixed":"7.4.6"}]}}],"versions":["7.0.22rc3","7.4.6rc2","7.4.6rc1","7.0.22rc2","7.0.22rc1","7.0.20","7.0.21","7.4.5","7.4.4","7.0.20rc1","7.4.4rc1","7.0.19","7.4.3","7.4.3rc1","7.0.19rc1","7.4.2","7.0.18","7.0.18rc2","7.4.2rc2","7.0.18rc1","7.4.2rc1","7.4.1","7.0.17","7.4.1rc1","7.0.17rc2","7.0.17rc1","7.0.16","7.0.15","7.4.0","7.0.14","7.0.14rc1","7.0.13","7.0.13rc1","7.0.12","7.0.12rc1","7.0.11","7.0.11rc2","7.0.11rc1","7.0.10","7.0.10rc1","7.0.9","7.0.9rc2","7.0.9rc1","7.0.8","7.0.8rc2","7.0.8rc1","7.0.7","7.0.7rc1","7.0.6","7.0.6rc1","7.0.5","7.0.5rc1","7.0.4","7.0.4rc1","7.0.3","7.0.3rc1","7.0.2","7.0.2rc2","7.0.2rc1","7.0.1","7.0.1rc2","7.0.1rc1","7.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23921.json","vanir_signatures_modified":"2026-09-12T08:14:50Z","vanir_signatures":[{"target":{"file":"src/zabbix_java/src/com/zabbix/gateway/GeneralInformation.java"},"deprecated":false,"digest":{"threshold":0.9,"line_hashes":["335575185657139336988338025089072345512","144097728509264372924349761206701036791","185724688006201679055704973376898360796","130162026250320242787979560813111933511","70354792077183199662061649065794713982","152321436213664381476643075846246568564"]},"id":"CVE-2026-23921-6d3c1d38","signature_type":"Line","signature_version":"v1","source":"https://github.com/zabbix/zabbix/commit/626d2b8a4820a424efe8fd39df3b706468f1e5d4"},{"source":"https://github.com/zabbix/zabbix/commit/ba52e2ee4ff8768c8450819a772886d79dcde0b4","target":{"file":"src/zabbix_java/src/com/zabbix/gateway/GeneralInformation.java"},"deprecated":false,"digest":{"line_hashes":["335575185657139336988338025089072345512","144097728509264372924349761206701036791","265387215296323665047876836033014923187","72110328909359773811350994976134420490","245919019046659487345219626549275780890","41189996272314509887159037345751552815"],"threshold":0.9},"id":"CVE-2026-23921-8066b192","signature_type":"Line","signature_version":"v1"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
