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.","publishedAt":"2026-03-27T00:30:02.069Z","updatedAt":"2026-03-27T19:59:15.920Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["opensourcepos opensourcepos"],"affected":[{"vendor":"opensourcepos","product":"opensourcepos","versions":[{"version":"< 3.4.2","status":"affected"}]}],"references":["https://github.com/opensourcepos/opensourcepos/security/advisories/GHSA-mcc2-8rp2-q6ch","https://github.com/opensourcepos/opensourcepos/commit/ee4d44ed396097d6010c5490ab4fd7cfae694624"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33730.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33730","state":"PUBLISHED","datePublished":"2026-03-27T00:30:02.069Z","dateUpdated":"2026-03-27T19:59:15.920Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-23T17:34:57.560Z"},"containers":{"cna":{"title":"Open Source Point of Sale has an IDOR in Password Change (Home)","descriptions":[{"lang":"en","value":"Open Source Point of Sale (opensourcepos) is a web based point of sale application written in PHP using CodeIgniter framework.
