In versions prior to 2026.7, the REST API did not properly enforce the scope of project- and workspace-scoped teams, allowing a user to submit invalid team configurations through the API. By assigning projects to a team via these unvalidated requests, a user could grant access to projects they were not authorized to see or manage. This could expose private projects and permit translation, repository, and project-management operations outside the user's intended permission scope. This issue is fixed in version 2026.7.","published":"2026-08-26T20:14:02.713Z","modified":"2026-09-11T03:31:01.382284530Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"weblate","fixedVersion":"2026.7"}],"fix":{"url":"https://github.com/WeblateOrg/weblate/commit/19babc99b05f2cc299b5090f90f79d8181f25d79","label":"WeblateOrg/weblate@19babc9"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55228.json"},{"type":"ADVISORY","url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-2q2q-jr9g-v9rf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55228"},{"type":"FIX","url":"https://github.com/WeblateOrg/weblate/commit/19babc99b05f2cc299b5090f90f79d8181f25d79"},{"type":"WEB","url":"https://github.com/WeblateOrg/weblate/pull/19970"},{"type":"PACKAGE","url":"https://github.com/WeblateOrg/weblate"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:31:01.382284530Z"}}
