NVD · unedited
Wolf CMS through 0.8.3.1 contains an authorization bypass vulnerability in BackupRestoreController that allows authenticated non-administrative users to access restricted backup functionality due to a PHP operator precedence flaw in the permission check expression. Attackers can exploit the incorrect evaluation of the access control expression to create, download, and restore backups without administrative privileges.

dbcve analysis · high confidence
Wolf CMS through 0.8.3.1 has an authorization bypass in BackupRestoreController where a PHP operator precedence flaw causes the permission check expression to evaluate incorrectly, allowing authenticated non-administrative users to create, download, and restore backups.
MitigationFix the operator precedence in the permission check expression in BackupRestoreController.php, or upgrade to a patched version if available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Identify Wolf CMS installation
Locate Wolf CMS files in the webroot; look for characteristic directories such as 'wolf' or 'app' and a file named 'index.php' that includes Wolf CMS initialization code.
Affected if Wolf CMS is present on the server.
Determine installed Wolf CMS version
Search for a version identifier in Wolf CMS core files; common locations include a version.php file, the main config file, or a CHANGELOG/CHANGES file in the CMS root directory.
Affected if The installed version is 0.8.3.1 or any earlier version through the 0.8.x line.
Locate the BackupRestoreController file
Navigate to the application controller directory (commonly /wolf/app/controller/ or similar MVC path) and identify BackupRestoreController.php or a file handling backup and restore operations.
Affected if The BackupRestoreController file exists and is accessible within the Wolf CMS installation.
Examine the permission check expression in BackupRestoreController
Open the BackupRestoreController file and locate the permission check logic that governs access to create, download, and restore backup functions; inspect the conditional expression for operator precedence issues (for example, a flaw where AND/OR operators are not properly grouped with parentheses).
Affected if The permission check uses an expression where operator precedence causes the access control to evaluate incorrectly, allowing authenticated non-administrator users to pass the check.
Verify non-administrator user access to backup functions
Using a test authenticated user account with non-administrator privileges, attempt to access or trigger backup creation, download, or restore endpoints provided by BackupRestoreController; observe whether the actions execute without permission errors.
Affected if Non-administrator users can successfully create, download, or restore backups despite lacking administrative privileges.
A Wolf CMS installation at version 0.8.3.1 or earlier with a flawed permission check expression in BackupRestoreController that allows authenticated non-administrative users to access backup functions is affected by this vulnerability.

Mitigation availableNo clean upgrade yet — mitigate in the meantime
Mitigation
Fix the operator precedence in the permission check expression in BackupRestoreController.php, or upgrade to a patched version if available.
Recommended fixModerate confidence
Wolf CMS 0.8.4 or latest stable release
1. Verify current Wolf CMS version by checking the version file or admin dashboard
2. Navigate to the official Wolf CMS repository or download page
3. Download the latest stable release (version 0.8.4 or later if available)
4. Backup the current database and all files before upgrading
5. Replace core files with the new version, preserving custom themes and plugins
6. Test backup and restore functionality to confirm the authorization fix works correctly
7. Verify that non-administrative users can no longer access backup/restore functions
Caveat Review changelog for any breaking changes between 0.8.3.1 and the target version; custom themes/plugins may require updates

The CVE-2026-67207 vulnerability in Wolf CMS versions up to 0.8.3.1 stems from a PHP operator precedence error in BackupRestoreController that allows authenticated users without admin privileges to create, download, and restore backups. The flawed expression uses incorrect operator precedence that evaluates an authorization check incorrectly—specifically, it treats the permission check as a logical OR when it should be AND, allowing the backup operations to proceed when either authentication succeeds OR the role check evaluates falsely due to precedence.
The practical impact is significant: an attacker with any valid user account can extract the entire database, configuration files (including potential secret keys), and potentially other user data through the backup restore chain. This transforms a standard user account into full system compromise.
Two factors work in your favor: the EPSS score of 0.003 suggests the vulnerable code path isn't commonly reached in typical deployments, likely because backup functionality isn't frequently accessed. However, this should not inspire complacency—if your Wolf CMS deployment exposes backup functionality to authenticated users, the blast radius of a successful exploit is high.
What to do: First, audit whether your Wolf CMS instance exposes the /backup_restore endpoint to non-admin users. Second, check user role configurations—ensure no roles with limited permissions have access to backup operations. Third, consider network-level restrictions on backup endpoints if they're not business-required. Fourth, evaluate migration: Wolf CMS 0.8.3.1 appears largely unmaintained, meaning upstream security patches may never arrive. If you're running this in production, treat the absence of a vendor patch as a forcing function for migration planning rather than waiting for one that may never come.
The operator precedence pattern itself is worth tracking: PHP authentication bypasses stemming from precedence errors have recurred across multiple codebases and years. Treat this CVE as evidence that any permission check expression involving multiple operators warrants explicit parentheses regardless of correctness—cognitive traps in boolean logic are a recurring PHP vulnerability class.
