Is Strict CSP Safe to Use in 2026?
Generally Safe
Score 100/100Strict CSP has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The "strict-csp" plugin version 0.3.2 exhibits an exceptionally strong security posture based on the provided static analysis and vulnerability history. The absence of any identified attack surface, dangerous functions, unsanitized taint flows, or direct SQL queries is a significant strength. Furthermore, the plugin appears to handle output properly and avoid file operations or external HTTP requests. This suggests a well-developed and secure codebase, with a strong focus on defensive programming practices.
The lack of any recorded vulnerabilities, past or present, reinforces this positive assessment. There are no unpatched CVEs, and the plugin has not historically been associated with common vulnerability types. This track record indicates a commitment to security by the developers or a lack of past attempts to exploit it, which, combined with the clean code analysis, suggests a low overall risk profile.
While the data paints a picture of a very secure plugin, the complete absence of capability checks and nonce checks on its entry points (even though there are zero entry points identified) is a theoretical concern. If any new entry points were to be introduced in future versions without proper authorization mechanisms, this could create an immediate risk. However, based on the current analysis, this plugin appears to be a highly secure option.
Key Concerns
- No capability checks identified
- No nonce checks identified
