Deeper analysis

CVE-2025-52746 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the ayecode Restaurante WordPress theme. It affects the Restaurante theme from unknown initial versions (n/a) through 3.0.7.

The vulnerability carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating exploitation is possible over the network with low attack complexity, no privileges required, but user interaction needed. Remote attackers can exploit it by tricking authenticated users, such as site visitors or administrators, into interacting with malicious payloads, such as crafted links or inputs reflected in web pages. Successful exploitation enables limited impacts on confidentiality, integrity, and availability with changed scope, potentially allowing session hijacking or similar actions.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Theme/restaurante/vulnerability/wordpress-restaurante-theme-3-0-7-cross-site-scripting-xss-vulnerability?_s_id=cve documents the issue specifically in Restaurante theme version 3.0.7 and provides details for security practitioners on the XSS vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and sanitization of untrusted input before it is used in web page generation, blocking the reflected XSS payload in CVE-2025-52746.

SI-15 Information Output Filtering good match
prevent

Requires filtering or encoding of information outputs so that reflected script content is neutralized before reaching the browser.

AC-4 Information Flow Enforcement partial match
prevent

Enforces information flow rules that can prevent untrusted, unsanitized data from being written into HTTP responses.
