Deeper analysis
CVE-2026-32426 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98, affecting the Medilazar Core WordPress plugin developed by themelexus. Specifically, it enables PHP Local File Inclusion despite being described as a PHP Remote File Inclusion issue. The vulnerability impacts all versions of Medilazar Core from n/a through those prior to 1.4.7. It carries a CVSS v3.1 base score of 7.5 (High), with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility but high attack complexity.
Attackers with low privileges, such as authenticated users with limited roles on a vulnerable WordPress site, can exploit this remotely over the network without user interaction. Successful exploitation allows high-impact confidentiality, integrity, and availability violations, potentially enabling attackers to read sensitive local files, execute arbitrary code via included files, modify site data, or disrupt service.
The Patchstack advisory confirms the Local File Inclusion vulnerability in the Medilazar Core plugin and recommends updating to version 1.4.7 or later to mitigate it, as prior versions remain susceptible.
