What is CVE-2026-47277?
CVE-2026-47277 is a medium-severity path traversal vulnerability in runtipi, published on 16 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Runtipi is a personal homeserver orchestrator. In versions 4.9.1 through 4.9.3, Runtipi serves marketplace app logos from files inside cloned app-store repositories through an unauthenticated endpoint, which leads to arbitrary file read through app-store logo symlinks. The path guard checks only the lexical path before Node reads the file, so a Git app store that contains metadata/logo.jpg as a symbolic link can cause Runtipi to read and return the symlink target. Because the endpoint is public and the symlink target may point outside the cloned repository, this can expose local files from the Runtipi container such as /data/.env, /data/state/seed, logs, or application files. This can disclose JWT secrets, service credentials, local configuration, and operational logs depending on the instance. The issue has been fixed in version 4.10.0.
