Summary
A security vulnerability in Cockpit CMS up to version 0.12.2 affects the Spyc::YAMLLoad function in the /config/config.yaml file of the htaccess Handler component. This manipulation leads to unauthorized access to files or directories. The attack can be launched remotely and the exploit has been publicly disclosed.
Risk Assessment
The organization is at risk of remote access to sensitive configuration files and data, potentially leading to information disclosure or further attack escalation.
Recommendation
Immediately change the Cockpit CMS configuration settings and consider updating to a newer version if available. Due to the vendor's lack of response, it is recommended to temporarily disable or secure the htaccess Handler component.
Other vulnerabilities in Cockpit CMS
See all- CVE-2026-82449Medium
Cockpit CMS before version 2.14.1 contains an account enumeration vulnerability in the auth check endpoint due to timing discrepancies in password verification. Attackers can measure response times across multiple requests to determine which accounts exist by observing that existing accounts trigger bcrypt verification while non-existent accounts return immediately.
- CVE-2026-72557High
An unrestricted file upload vulnerability in Cockpit CMS 2.6.0 allows authenticated users to upload files of any extension including PHP scripts via the asset upload endpoint. The allowed_uploads defaults to wildcard and files are stored in a web-accessible directory.
- CVE-2026-39275Medium
A Cross Site Scripting vulnerability in Cockpit CMS v.2.13.5 and before allows a remote attacker to execute arbitrary code in the victim's browser via the item.php, field-select.js and tags.js components.
- CVE-2026-73680High
Cockpit CMS 2.14.0 and prior contains a command injection vulnerability in the FFmpeg integration that allows authenticated users with only the assets/upload permission to execute arbitrary commands by uploading a video file with a shell metacharacter-laden filename. The unsanitized filename is interpolated into a shell command executed via Process::fromShellCommandline() before the slugify() sanitizer runs, enabling injected shell metacharacters such as backticks, $(), and semicolons to escape the FFmpeg command context and execute as the web-server user.
- CVE-2026-57856High
A path traversal vulnerability was found in Cockpit CMS's Bucket file storage API (/system/buckets/api). The api() method in modules/System/Controller/Buckets.php sanitizes the bucket name with preg_replace('/[^a-zA-Z0-9-_\.]/','', $bucket), which permits '..' and '../' sequences. The sanitized value is interpolated into a Flysystem path as uploads://buckets/{bucket}, and the WhitespacePathNormalizer resolves 'buckets/..' to the empty string (the uploads storage root) without raising PathTraversalDetected because the '..' has a preceding component to consume.
- CVE-2026-57855High
Cockpit CMS has a missing authorization vulnerability in the Bucket file storage API (/system/buckets/api). The api() method in modules/System/Controller/Buckets.php executes bucket commands (ls, upload, removefiles, rename, createfolder) without any ACL or role check. Any authenticated user, regardless of role, can perform all bucket operations on any named bucket, including buckets intended for admin use only.
- CVE-2026-58467High
Cockpit CMS up to version 2.14.0 contains a path traversal and local file inclusion (LFI) vulnerability. Unauthenticated attackers can read arbitrary files or execute PHP code by injecting unvalidated PATH_INFO from REQUEST_URI into filesystem path construction without containment checks.
- CVE-2026-23695Medium
Cockpit CMS up to version 2.14.0 contains a stored cross-site scripting vulnerability in the Set field type's Display template option. The template string is processed by the $interpolate function using new Function() and rendered via Vue's v-html directive without sanitization, allowing an attacker with content/:models/manage permission to inject arbitrary JavaScript.
- CVE-2023-37650High
A Cross-Site Request Forgery (CSRF) in the Admin portal of Cockpit CMS v2.5.2 allows attackers to execute arbitrary Administrator commands.
