Prior to version 2.51.0, \"GET /api/invoices/{id}\" only checks the role-based view_invoice permission but does not verify the requesting user has access to the invoice's customer. Any user with ROLE_TEAMLEAD (which grants view_invoice) can read all invoices in the system, including those belonging to customers assigned to other teams. This issue has been patched in version 2.51.0.","published":"2026-03-06T04:49:08.312Z","modified":"2026-07-15T01:49:21.280032756Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"kimai/kimai","fixedVersion":"2.51.0"}],"fix":{"url":"https://github.com/kimai/kimai/commit/a0601c8cb28fed1cca19051a8272425069ab758f","label":"kimai/kimai@a0601c8"},"references":[{"type":"WEB","url":"https://github.com/kimai/kimai/releases/tag/2.51.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28685.json"},{"type":"ADVISORY","url":"https://github.com/kimai/kimai/security/advisories/GHSA-v33r-r6h2-8wr7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28685"},{"type":"FIX","url":"https://github.com/kimai/kimai/commit/a0601c8cb28fed1cca19051a8272425069ab758f"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:21.280032756Z"}}
