Deeper analysis

CVE-2025-69367 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling DOM-based Cross-site Scripting (XSS, CWE-79), in the GT3themes Oyster - Photography WordPress Theme. The issue affects the Oyster theme from unknown initial versions through version 4.4.3 inclusive. Published on 2026-02-20, it carries a CVSS v3.1 base score of 7.1.

Attackers can exploit this remotely over the network (AV:N) with low complexity (AC:L) and no required privileges (PR:N), though user interaction is necessary (UI:R). Exploitation changes scope (S:C), potentially leading to low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), such as executing scripts in the victim's browser context via manipulated inputs during web page generation.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Theme/oyster/vulnerability/wordpress-oyster-photography-wordpress-theme-theme-4-4-3-cross-site-scripting-xss-vulnerability?_s_id=cve provides details on this vulnerability in the Oyster theme up to version 4.4.3.
