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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-918"],"references":["https://github.com/learningequality/kolibri/releases/tag/v0.19.4","https://github.com/learningequality/kolibri/security/advisories/GHSA-4mj9-pf4r-cqrc","https://github.com/pypa/advisory-database/tree/main/vulns/kolibri/PYSEC-2026-2554.yaml","https://github.com/learningequality/kolibri/security/advisories/GHSA-4mj9-pf4r-cqrc"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-48053","score":0.00384,"percentile":0.32205,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4mj9-pf4r-cqrc","url":"https://osv.dev/vulnerability/GHSA-4mj9-pf4r-cqrc","summary":"Kolibri has Unauthenticated Server-Side Request Forgery (SSRF) in RemoteFacilityUserViewset","modified":"2026-07-13T16:43:42.878037480Z","packages":[{"ecosystem":"PyPI","name":"kolibri","purl":"pkg:pypi/kolibri","ranges":["<0.19.4"],"fixed":["0.19.4"]}]},{"id":"PYSEC-2026-2554","url":"https://osv.dev/vulnerability/PYSEC-2026-2554","summary":"Kolibri has Unauthenticated Server-Side Request Forgery (SSRF) in RemoteFacilityUserViewset","modified":"2026-07-13T16:31:48.605331962Z","packages":[{"ecosystem":"PyPI","name":"kolibri","purl":"pkg:pypi/kolibri","ranges":["<0.19.4"],"fixed":["0.19.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
