CVE-2026-47277: Runtipi is a personal homeserver orchestrator.

Runtipi is a personal homeserver orchestrator.

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.

What it means for a small business

If your business uses runtipi, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.40%, higher than 34% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
