{"id":"CVE-2026-63221","aliases":["GHSA-c9w5-rwh3-7pm9"],"url":"https://o3.security/vulnerability/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.","published":"2026-07-31T04:03:34.352Z","modified":"2026-09-10T03:31:02.725864572Z","cvss":{"score":9.4,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H"},"epss":{"score":0.00372,"percentile":0.30951,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"codeigniter4/framework","fixedVersion":"4.7.4"}],"fix":{"url":"https://github.com/codeigniter4/CodeIgniter4/commit/f5e463b9a3e986389ce285963e51a7f1fab6559f","label":"codeigniter4/CodeIgniter4@f5e463b"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:31:02.725864572Z"}}
