Is Post Grid Gutenberg Blocks for News, Magazines, Blog Websites – PostX Safe to Use in 2026?
Generally Safe
Score 88/100Post Grid Gutenberg Blocks for News, Magazines, Blog Websites – PostX has a strong security track record. Known vulnerabilities have been patched promptly. It's a solid choice for most WordPress installations.
The 'ultimate-post' plugin version 5.0.11 presents a mixed security posture. While it demonstrates good practices such as extensive use of prepared statements for SQL queries (95%) and a high rate of proper output escaping (84%), significant concerns arise from its attack surface. A large number of entry points, specifically 34 out of 52, lack proper authentication or permission checks. This includes a substantial portion of its REST API routes (31 without permission callbacks) and several AJAX handlers (3 without auth checks), creating numerous potential avenues for unauthorized access and exploitation.
The historical vulnerability data is a major red flag, with a staggering 23 known CVEs, 6 of which are high severity. The common vulnerability types, including SSRF, Information Exposure, Improper Privilege Management, Missing Authorization, and XSS, directly correlate with the identified weaknesses in the static analysis, particularly the lack of robust authorization checks on entry points. The fact that the last vulnerability was as recent as March 2026, even though it is marked as unpatched (which contradicts the '0 unpatched' data point and suggests a potential data inconsistency or a future vulnerability already accounted for), indicates a recurring pattern of security flaws within the plugin. While the current static analysis did not reveal critical taint flows or dangerous functions, the historical context and the exposed attack surface are serious indicators of potential risk.
In conclusion, despite some commendable secure coding practices, the 'ultimate-post' plugin has a history of significant security issues and possesses a large, unprotected attack surface. This combination makes it a high-risk plugin that requires immediate attention. Developers should prioritize auditing and securing all AJAX handlers and REST API routes, and users should be extremely cautious when deploying this version.
