How do I ensure third-party scripts don’t weaken my CSP?

Asked on Oct 06, 2025

Answer

To ensure third-party scripts don't weaken your Content Security Policy (CSP), you should carefully define and limit the sources from which scripts can be loaded. This helps prevent malicious code execution.

Example Concept: A Content Security Policy (CSP) is a security feature that helps prevent a variety of attacks, such as Cross-Site Scripting (XSS) and data injection attacks. By specifying allowed sources for content, CSP reduces the risk of executing malicious scripts. Use directives like 'script-src' to control script sources and 'nonce-' or 'sha-' for inline scripts.

Additional Comment:

Use nonces or hashes for inline scripts to ensure only intended scripts are executed.
Regularly review and update your CSP to include only trusted third-party domains.
Consider using the 'report-uri' directive to monitor and report CSP violations.
