# Cockpit storage: crafted LUKS header injects curl options into Tang settings

Link for people: https://infrastack.ai/live/CVE-2026-125672 (this .md is for agents)

Cockpit's storage module passes a Tang keyserver address from a LUKS/clevis header to curl without a separator, so an address starting with a dash is read as a curl option. An attacker who can attach a crafted encrypted device can get an admin user to trigger arbitrary file read or write as that Cockpit session user.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

A flaw was found in cockpit-storaged. A Tang keyserver address read from a clevis token in a LUKS header is concatenated into curl's argument vector without a "--" separator. An address beginning with "-" is parsed by curl as an option instead of a hostname, allowing an attacker who can attach a crafted LUKS/clevis block device (for example, a local unprivileged user with an active console or desktop login session) to have an administratively-privileged Cockpit user unknowingly trigger curl option injection when editing the device's Tang keyserver settings. This can lead to arbitrary file read or write as the Cockpit session user.
