Detailsinfo

A vulnerability classified as critical has been found in LaraDashboard up to 1.2.2. This affects the function BackupService::deleteBackup of the file storage/app/core-backups of the component Core Upgrade Backup Handler. The manipulation of the argument backup_file with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

LaraDashboard versions 0.9.2 through 1.2.2 contain a path traversal vulnerability in the core-upgrade backup handling. CoreUpgradeController and BackupService (e.g. BackupService::deleteBackup()) concatenate the user-supplied backup_file/filename value directly onto the backup directory path without normalisation, without applying basename(), and without verifying that the resolved path remains inside storage/app/core-backups; the corresponding form requests only validate the value as a bounded string. An authenticated user holding only the delegated settings.edit permission (not Superadmin) can supply ../ traversal sequences to delete arbitrary files reachable on the host filesystem, including outside the application tree, or to restore a ZIP archive from an arbitrary on-disk location, writing arbitrary files into the application directories and achieving remote code execution. Note: the advisory states the vulnerable concatenation was introduced in the v0.9.7 release line. No patched version was available at the time of publication.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-90932 since 09/14/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/14/2026). MITRE ATT&CK project uses the attack technique T1006 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
