Detailsinfo

A vulnerability, which was classified as critical, was found in MiniGal Nano up to 0.3.5. Affected is an unknown part of the file index.php. The manipulation of the argument dir 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. CVE summarizes:

MiniGal Nano versions 0.3.5 and prior contain a path traversal vulnerability in index.php via the dir parameter. The application appends user-controlled input to the photos directory and attempts to prevent traversal by removing dot-dot sequences, but this protection can be bypassed using crafted directory patterns. An attacker can exploit this behavior to cause the application to enumerate and display image files from unintended filesystem locations that are readable by the web server, resulting in unintended information disclosure.

The weakness was presented by philopentest. The advisory is available at web.archive.org. This vulnerability is traded as CVE-2026-25869 since 02/06/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/16/2026).
