Deeper analysis

CVE-2025-39484 is an SQL Injection vulnerability (CWE-89) stemming from improper neutralization of special elements used in an SQL command. It affects the Waituk Entrada WordPress theme, specifically versions from n/a through 5.7.7. The vulnerability was published on 2026-01-05 and carries a CVSS v3.1 base score of 9.3 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L), marking it as critical.

Remote unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Exploitation allows attackers to inject malicious SQL queries, resulting in high confidentiality impact through unauthorized data access, low availability impact, and a scope change that affects other system components.

Advisories, such as the Patchstack database entry (https://patchstack.com/database/Wordpress/Theme/entrada/vulnerability/wordpress-entrada-theme-5-7-7-sql-injection-vulnerability?_s_id=cve), provide details on the vulnerability in the Entrada theme version 5.7.7.
