{"apiVersion":"1.0","identifier":"CVE-2026-48053","description":"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.","publishedAt":"2026-08-17T18:16:39","lastModifiedAt":"2026-08-17T20:16:43","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48053","cvssScore":5.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","epssProbability":0.00282,"riskScore":0.59,"affectedProduct":"Kolibri","affectedVersions":"<0.19.4","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-48053","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-48053","en":"https://www.redsauce.net/en/cves/CVE-2026-48053","fr":"https://www.redsauce.net/fr/cves/CVE-2026-48053","pt":"https://www.redsauce.net/pt/cves/CVE-2026-48053","de":"https://www.redsauce.net/de/cves/CVE-2026-48053","sk":"https://www.redsauce.net/sk/cves/CVE-2026-48053","el":"https://www.redsauce.net/el/cves/CVE-2026-48053"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-48053"}}
