The vulnerability CVE-2025-57889 affects RealMag777's InPost Gallery software, specifically versions up to 2.1.4.5. It arises from improper control over filenames used in PHP include or require statements, enabling PHP Local File Inclusion. This can allow an attacker with low privileges and no user interaction to execute arbitrary code or access sensitive files on the server. The CVSS 3.1 vector indicates network attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to full compromise of the affected system's confidentiality, integrity, and availability. An attacker could potentially execute arbitrary PHP code or access sensitive files, resulting in data disclosure, modification, or denial of service. The CVSS score of 7.5 reflects these high impacts. There are no reports of known exploits in the wild at this time.
