Detailsinfo

A vulnerability classified as problematic has been found in givanz Vvveb up to 1.0.8.6. Affected is the function nextRestore/nextBackup of the file backup controller of the component Backup Controller. The manipulation of the argument 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. CVE summarizes:

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. In versions 1.0.8.6 and prior, the nextRestore() and nextBackup() functions in the backup controller accept a file GET parameter and concatenate it directly to DIR_BACKUP without calling sanitizeFileName(). This allows an authenticated administrator to read arbitrary files on the server (via nextRestore) and write SQL dump content to arbitrary locations (via nextBackup). This is inconsistent with the sibling functions restore(), delete(), and download() which all correctly call sanitizeFileName() first. This issue has been patched via commit aa29cb0.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-112904 since 10/19/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are needed for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

Applying the patch aa29cb013e5037d75f6780741bac6b69b9d403a2 is able to eliminate this problem.
