Hi,
The following vulnerability was published for cockpit-files.
CVE-2026-91203[0]:
| A flaw was found in cockpit-files. This vulnerability allows a local
| attacker to exploit a timing issue, known as a symlink race
| condition, during privileged file operations such as changing file
| ownership or permissions. By manipulating directory entries and
| winning this race, the attacker can redirect these operations to
| unintended files. This could lead to unauthorized changes in file
| ownership and permissions on arbitrary files, potentially
| compromising system integrity and availability by altering system or
| application states or rendering services unusable.
