Deeper analysis
CVE-2026-27348 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as DOM-Based Cross-site Scripting (XSS, CWE-79), in the ThemeGoods Photography WordPress theme. Published on 2026-03-05, it affects all versions of the Photography theme from n/a through those prior to 7.7.6.
The vulnerability carries a CVSS v3.1 base score of 7.1 (High), with attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). Successful exploitation changes scope (S:C) and results in low impacts to confidentiality, integrity, and availability (C:L/I:L/A:L). Remote attackers can exploit it by tricking authenticated users into interacting with malicious content, such as crafted links or inputs, to inject and execute scripts in the victim's browser context.
