Summary
Cockpit CMS 2.14.1 contains an observable timing discrepancy vulnerability that allows unauthenticated attackers to enumerate accounts due to an incomplete timing fix in /auth/check. Attackers can post login attempts and measure response times, since existing accounts incur two bcrypt operations versus one, revealing valid usernames and email addresses.
Risk Assessment
The organization may be exposed to account enumeration, which facilitates targeted attacks such as phishing or brute force. Disclosure of valid usernames and email addresses increases the risk of account compromise.
Recommendation
Upgrade Cockpit CMS to a version that fully addresses the timing discrepancy in /auth/check, or implement additional rate-limiting and delay mechanisms. Monitor for unusual login activity and consider deploying multi-factor authentication.
Other vulnerabilities in Cockpit CMS
See all- CVE-2026-105217Low
Cockpit CMS 2.12.0 before 2.14.1 disables TLS certificate verification in the cron.php web worker restart request, allowing network attackers to capture the worker token. Man-in-the-middle attackers on the outbound path to site_url can present any certificate to steal the worker/web/token value and start the web worker.
- 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-2026-39275Medium
Cross Site Scripting vulnerability in Cockpit CMS v.2.13.5 and before allows a remote attacker to execute arbitrary code 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-2026-72557High
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-2026-57856High
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-2026-13533Medium
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.
- 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.
