Prior to version 0.19.4, several Kolibri API endpoints accept an unvalidated `baseurl` parameter and fetch attacker-controlled URLs from the Kolibri server, reflecting the response body back to the caller. The original report identified two endpoints on the `RemoteFacilityUser*` viewsets; remediation review found two further reflection points on the same pattern. The GET endpoint was unauthenticated. Version 0.19.4 fixes the vulnerability.","published":"2026-08-17T17:57:05.139Z","modified":"2026-08-19T03:48:19.583891517Z","cvss":{"score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"},"epss":{"score":0.00282,"percentile":0.20111,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"kolibri","fixedVersion":"0.19.4"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/learningequality/kolibri/releases/tag/v0.19.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48053.json"},{"type":"ADVISORY","url":"https://github.com/learningequality/kolibri/security/advisories/GHSA-4mj9-pf4r-cqrc"},{"type":"ADVISORY","url":"https://github.com/pypa/advisory-database/tree/main/vulns/kolibri/PYSEC-2026-2554.yaml"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48053"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T03:48:19.583891517Z"}}
