CVE-2026-25116Public exploitNetwork attack vectorHinoki check available

Unauthenticated code execution via unsanitized URN path

Published Jan 29, 2026 · Updated Jan 29, 2026

Path traversal in Runtipi 4.5.0 through 4.7.1 allows remote attackers to overwrite the main Docker Compose file without authentication. The updateUserConfig endpoint lacks AuthGuard, while extractAppUrn passes traversal segments from the urn parameter into AppFilesManager path.join resolution. Execution requires an operator to restart the instance outside the CLI, after which the injected Compose service runs attacker-controlled code with host filesystem access.
