{"apiVersion":"1.0","identifier":"CVE-2026-55168","description":"Runtipi is a personal homeserver orchestrator. In 4.10.0 and earlier, Runtipi accepts symbolic links from an attacker-controlled backup archive and copies them into live application paths during the backup restore flow. An authenticated attacker can plant user-config/app.env as a symlink to an arbitrary reachable path and then send PUT /api/user-config/demoapp3:_user with attacker-controlled appEnv content. FilesystemService.writeTextFile() follows the planted link, allowing content to be written outside the intended restore and user-config directory boundary with Runtipi process permissions. This issue is fixed in version 4.10.1.","publishedAt":"2026-08-21T21:17:00","lastModifiedAt":"2026-08-25T17:17:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55168","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","epssProbability":0.00528,"riskScore":0.68,"affectedProduct":"Runtipi","affectedVersions":"<=4.10.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-55168","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-55168","en":"https://www.redsauce.net/en/cves/CVE-2026-55168","fr":"https://www.redsauce.net/fr/cves/CVE-2026-55168","pt":"https://www.redsauce.net/pt/cves/CVE-2026-55168","de":"https://www.redsauce.net/de/cves/CVE-2026-55168","sk":"https://www.redsauce.net/sk/cves/CVE-2026-55168","el":"https://www.redsauce.net/el/cves/CVE-2026-55168"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-55168"}}
