Deeper analysis
CVE-2026-28048 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, described as PHP Remote File Inclusion but enabling PHP Local File Inclusion, affecting the magentech FlashMart WordPress theme in versions from n/a through 2.0.15. This flaw, tied to CWE-98, stems from inadequate validation of filenames in PHP include/require statements within the theme.
The vulnerability carries a CVSS 3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating exploitation over the network by unauthenticated attackers without user interaction, though it requires high attack complexity. Successful exploitation allows attackers to include arbitrary local files, potentially resulting in high-impact confidentiality violations through data disclosure, integrity compromises via file manipulation, and availability disruptions, with risks escalating to remote code execution if executable PHP files are included.
