Deeper analysis
CVE-2026-23975 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as a PHP Remote File Inclusion issue that enables PHP Local File Inclusion, affecting the uxper Golo WordPress theme in versions from n/a through less than 1.7.5. It is linked to CWE-98 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to significant impacts on confidentiality, integrity, and availability.
The vulnerability can be exploited over the network by an attacker with low privileges, such as an authenticated user, though it requires high attack complexity and no user interaction. Successful exploitation allows the attacker to include and execute arbitrary local PHP files, potentially leading to unauthorized access to sensitive data, modification of system files, or denial of service.
