Deeper analysis

CVE-2026-32537 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98, affecting the WordPress plugin Visual Portfolio, Photo Gallery & Post Grid (visual-portfolio) by nK. The issue enables PHP Local File Inclusion and impacts all versions from n/a through 3.5.1. It was published on 2026-03-25 with a CVSS v3.1 base score of 7.5 (High).

Attackers with low privileges (PR:L) can exploit this vulnerability over the network (AV:N), though it requires high attack complexity (AC:H) and no user interaction (UI:N). Successful exploitation allows high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within unchanged scope (S:U), enabling low-privileged authenticated users to perform local file inclusion on the targeted WordPress site.

Why these techniques?

LFI vuln in public-facing WordPress plugin directly enables T1190 (exploitation of the web app by low-priv authenticated users) and T1005 (arbitrary local file reads via include/require).
