{"id":"CVE-2026-63221","summary":"CodeIgniter: SQL injection is possible via Query Builder deleteBatch() when used with where() conditions","details":"CodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing user-controlled condition values to be interpreted as SQL. This affects only the deleteBatch() code path. Regular delete() operations escape where() binds correctly. This issue is fixed in version 4.7.4.","aliases":["GHSA-c9w5-rwh3-7pm9"],"modified":"2026-08-02T03:31:59.434312996Z","published":"2026-07-31T04:03:34.352Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63221.json"},"references":[{"type":"WEB","url":"https://github.com/codeigniter4/CodeIgniter4/releases/tag/v4.7.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63221.json"},{"type":"ADVISORY","url":"https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-c9w5-rwh3-7pm9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63221"},{"type":"FIX","url":"https://github.com/codeigniter4/CodeIgniter4/commit/f5e463b9a3e986389ce285963e51a7f1fab6559f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/codeigniter4/codeigniter4","events":[{"introduced":"f8e4ec57cb420e24c86e81eccef39c37ed257575"},{"fixed":"2bd0f01d2813f9ec06db42643ce39d9f5428bf6d"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"4.3.0"},{"fixed":"4.7.4"}]}}],"versions":["v4.7.3","v4.7.2","v4.7.1","v4.7.0","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.8","v4.5.7","v4.5.6","v4.5.5","v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.5.0","v4.4.8","v4.4.7","v4.4.6","v4.4.5","v4.4.4","v4.4.3","v4.4.2","v4.4.1","v4.4.0","v4.3.8","v4.3.7","v4.3.6","v4.3.5","v4.3.4","v4.3.3","v4.3.2","v4.3.1","v4.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63221.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H"}]}
