CVE-2026-80138: ClipBucket V5 installer lets anyone run commands on server
CVE-2026-80138 · published 9 days ago
Summary
The web installer in ClipBucket version 5 does not check a setting called php_cli_filepath before using it in a command line. This lets anyone on the internet send a specially crafted request to the installer and cause it to run any command they choose with the same rights as the website. Update to a fixed version or disable the installer until it is patched.
