Is LinkGuard NT Safe to Use in 2026?
Generally Safe
Score 100/100LinkGuard NT has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The 'linkguard-nt' v1.0.0 plugin presents a mixed security posture. On the positive side, it boasts a clean vulnerability history with no known CVEs and a strong adherence to using prepared statements for SQL queries, with 88% of them properly secured. The limited number of file operations and external HTTP requests also contribute to a reduced attack surface in those areas. However, significant concerns arise from the large number of unprotected AJAX handlers. With 9 out of 9 AJAX handlers lacking authentication checks, this represents a critical weakness, potentially allowing unauthenticated users to trigger sensitive actions.
The taint analysis reveals two flows with unsanitized paths, classified as high severity. This, combined with the aforementioned unprotected AJAX handlers, suggests a real risk of cross-site scripting (XSS) or path traversal vulnerabilities if user-supplied data is not properly validated and sanitized before being used in file operations or other sensitive functions. The output escaping is also a concern, with only 38% of outputs being properly escaped, further increasing the risk of XSS attacks.
While the plugin has no recorded vulnerability history, this should not be taken as a guarantee of security. The current code analysis reveals specific exploitable areas. The strengths in SQL handling and lack of historical vulnerabilities are overshadowed by the critical security flaws in AJAX handler protection and the high-severity taint flows. A balanced view indicates that while the plugin avoids common pitfalls like unpatched CVEs, its current implementation is vulnerable to serious attacks due to insufficient input validation and authorization checks on its entry points.
Key Concerns
- 9 unprotected AJAX handlers
- 2 unsanitized path taint flows (high severity)
- Low output escaping rate (38%)
- Only 4 capability checks for 10 entry points
