{"id":"CVE-2026-26745","details":"OpenSourcePOS 3.4.1 has a second order SQL Injection vulnerability in the handling of the currency_symbol configuration field. Although the input is initially stored without immediate execution, it is later concatenated into a dynamically constructed SQL query without proper sanitization or parameter binding. This allows an attacker with access to modify the currency_symbol value to inject arbitrary SQL expressions, which are executed when the affected query is subsequently processed.","modified":"2026-08-12T03:51:48.591021507Z","published":"2026-02-20T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26745.json"},"references":[{"type":"WEB","url":"https://github.com/hungnqdz/cve-research/blob/main/CVE-2026-26745.md"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26745.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26745"},{"type":"PACKAGE","url":"https://github.com/opensourcepos/opensourcepos"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensourcepos/opensourcepos","events":[{"introduced":"5f395d987b02562092b838073cb2e23a22d2bca4"},{"last_affected":"5f395d987b02562092b838073cb2e23a22d2bca4"}],"database_specific":{"extracted_events":[{"introduced":"3.4.1"},{"last_affected":"3.4.1"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:opensourcepos:open_source_point_of_sale:3.4.1:*:*:*:*:*:*:*"}}],"versions":["3.4.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-26745.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
