{"id":"CVE-2026-48053","summary":"Kolibri has Unauthenticated Server-Side Request Forgery (SSRF) in RemoteFacilityUserViewset","details":"Kolibri is an offline-first education platform. 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.","aliases":["GHSA-4mj9-pf4r-cqrc","PYSEC-2026-2554"],"modified":"2026-08-19T03:48:19.583891517Z","published":"2026-08-17T17:57:05.139Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48053.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/learningequality/kolibri","events":[{"introduced":"0"},{"fixed":"39ab253d6be88505bba43a6ae0684746c367c9c5"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.19.4"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.19.4-rc1","v0.19.4-rc0","v0.19.4-beta1","v0.19.4-alpha0","v0.19.0-beta2","v0.19.0-beta1","v0.19.0-beta0","v0.19.0-alpha1","v0.19.0-alpha0","v0.18.0-beta3","v0.18.0-beta2","npm/kolibri-tools/0.18.1","v0.18.0-beta1","v0.18.0-beta0","v0.18.0-alpha3","v0.18.0-alpha2","npm/kolibri-format/1.0.1","v0.18.0-alpha1","npm/kolibri-tools/0.18.0","npm/browserslist-config-kolibri/0.18.0","npm/kolibri-logging/1.0.0","npm/kolibri-format/1.0.0","npm/eslint-plugin-kolibri/0.18.0","v0.17.0-beta1","v0.17.0-beta0","v0.17.0-alpha0","v0.16.0-beta0","v0.16.0-alpha21","v0.16.0-alpha20","v0.16.0-alpha19","v0.16.0-alpha18","v0.16.0-alpha17","v0.16.0-alpha16","v0.16.0-alpha15","v0.16.0-alpha14","v0.16.0-alpha13","v0.16.0-alpha12","v0.16.0-alpha11","v0.16.0-alpha10","v0.16.0-alpha9","v0.16.0-alpha8","v0.16.0-alpha7","v0.16.0-alpha4","v0.16.0-alpha3","v0.16.0-alpha2","v0.16.0-alpha1","v0.15.0-alpha1","v0.15.0-alpha0","v0.14.0-alpha0","v0.13.0-alpha3","v0.13.0-alpha2","v0.13.0-alpha1","v0.13.0-alpha0","v0.12.4-beta0","v0.12.0-beta1","v0.12.0-alpha8","v0.12.0-alpha7","v0.12.0-alpha6","v0.12.0-alpha5","v0.12.0-alpha4","v0.12.0-alpha3","v0.12.0-alpha2","v0.12.0-alpha1","v0.11.0-alpha6","v0.11.0-alpha7","v0.11.0-alpha5","v0.11.0-alpha4","v0.11.0-alpha3","v0.11.0-alpha2","v0.11.0-alpha1","v0.10.0-alpha4","v0.10.0-alpha2","v0.10.0-alpha3","v0.10.0-alpha1","v0.9.1-beta2","v0.7.0-beta1","v0.6.0-beta2","v0.6.0-alpha1","v0.4.0-beta5","v0.4.0-beta1","v0.4.0-alpha7","v0.4.0-alpha6","v0.4.0-alpha5","v0.4.0-alpha4","v0.4.0-alpha1","v0.4.0-alpha3","v0.4.0-alpha2","v0.2.0-alpha2","v0.1.1-rc1","v0.0.1__mmvp","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48053.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}
