{"id":"CVE-2026-33730","summary":"Open Source Point of Sale has an IDOR in Password Change (Home)","details":"Open Source Point of Sale (opensourcepos) is a web based point of sale application written in PHP using CodeIgniter framework. Prior to version 3.4.2, an Insecure Direct Object Reference (IDOR) vulnerability allows an authenticated low-privileged user to access the password change functionality of other users, including administrators, by manipulating the `employee_id` parameter. The application does not verify object ownership or enforce authorization checks. Version 3.4.2 adds object-level authorization checks to validate that the current user owns the employee_id being accessed.","aliases":["GHSA-mcc2-8rp2-q6ch"],"modified":"2026-07-08T08:12:49.335977529Z","published":"2026-03-27T00:30:02.069Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33730.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33730.json"},{"type":"ADVISORY","url":"https://github.com/opensourcepos/opensourcepos/security/advisories/GHSA-mcc2-8rp2-q6ch"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33730"},{"type":"FIX","url":"https://github.com/opensourcepos/opensourcepos/commit/ee4d44ed396097d6010c5490ab4fd7cfae694624"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensourcepos/opensourcepos","events":[{"introduced":"0"},{"fixed":"849439c71eaa4c15857fb7c603297261c2ddc26d"},{"fixed":"ee4d44ed396097d6010c5490ab4fd7cfae694624"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:opensourcepos:open_source_point_of_sale:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.4.2"}]}}],"versions":["unstable","3.4.2","3.4.1","3.4.0","3.3.9","3.3.8","3.3.7","3.3.6","master.3.3.6","master.3.3.5","3.3.5","master.3.4.0-dev","3.3.4","3.3.3","3.3.2","3.3.1","3.3.0","3.2.0","3.1.1","3.1.0","3.0.2","3.0.1","3.0.0","2.4.0","2.3.4","2.3.3","2.3.2","2.3.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33730.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
