Hi @sharp bridge. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information in the knowledge sources, your CSP (Content Security Policy) issues in Nuxt are likely due to restrictive CSP directives that block inline scripts and external resources, such as images and third-party scripts. The errors you shared indicate:
- An inline script was blocked because its hash did not match the allowed hashes in your CSP.
- An external image (favicon) was blocked because the default-src directive is set to 'none', which blocks all external resources unless explicitly allowed.
Key Points from the Knowledge Sources:
- Nuxt CSP Support: Nuxt has introduced initial CSP handling, allowing you to configure CSP policies, including nonces and hashes. If you use the Nuxt Security module, its configuration takes precedence. However, documentation and full support (like route rules and hooks) are still in progress, so you may need to experiment with the available options or check for updates if you are on the latest Nuxt version. You can define policies and allow specific scripts or resources by hash, nonce, or source URL. If you use inline scripts, you must either add their hash to the policy or use a nonce mechanism if supported by your Nuxt version and setup. Similarly, for external resources (like images), you must add their domains to the appropriate directives (e.g., img-src, script-src) in your CSP configuration. If you set default-src to 'none', you must explicitly allow every resource type you need to load, or they will be blocked by default.

- Third-Party Scripts: Loading third-party scripts in Nuxt is a common scenario, and there are new modules (like nuxt/scripts) to help manage third-party assets and their CSP implications. If you are loading scripts dynamically or inline, you need to ensure your CSP allows them, either by using hashes, nonces, or by serving them from your own domain via Nitro.

What You Should Do:
- For Inline Scripts:
- Add the correct hash of your inline script to the script-src directive, or use a nonce if your Nuxt version and setup support it.
- For External Resources:
- Add the required domains (e.g., https://connect.visma.com for images) to the relevant directives (img-src, script-src, etc.).
- For Third-Party Scripts:
- Consider using the nuxt/scripts module to manage third-party scripts and their CSP requirements more easily.
Example CSP Adjustments:
// nuxt.config.ts (if using Nuxt Security module)
security: {
csp: {
// Example: Allow inline scripts by hash and allow images from specific domains
policies: {
'script-src': [
"'self'",
"'sha256-orD0/VhH8hLqrLxKHD/HUEMdwqX6/0ve7c5hspX5VJ8='", // Add your script's hash
// or use 'nonce-<your-nonce>' if supported
],
'img-src': [
"'self'",
"<https://connect.visma.com",>
],
// Add other directives as needed
}
}
}
Note: You must generate the correct hash for your inline script or use a nonce if your setup supports it. If you use default-src 'none', you must explicitly allow every resource type you need.
If you continue to have issues, double-check that your CSP settings are being applied as expected and that there are no typos or missing directives. Also, ensure that the Nuxt Security module is not being overridden elsewhere in your configuration.
If you need more detailed help, please provide your actual CSP configuration and the relevant part of your nuxt.config file.
In summary, your issue is due to restrictive CSP settings. Adjust your CSP to allow the required scripts and resources by adding the correct hashes, nonces, or domains as needed. The knowledge sources do not provide a step-by-step guide for every scenario, but they confirm that CSP configuration is possible and necessary in Nuxt, especially when dealing with third-party scripts and resources.

@kind canyon policies does not exist under nuxt-security unless I have to uninstall nuxt-security first?
kind canyonBOT
Let me check the knowledge base for you again. One moment! :books:
I'm sorry, but the knowledge sources do not contain explicit information about a policies property under nuxt-security or whether you need to uninstall nuxt-security to use it. The available sources mention that Nuxt has introduced initial CSP handling and that the Nuxt Security module's configuration takes precedence if installed, but they do not provide details about a policies option or its usage within nuxt-security. If you need precise configuration details, I recommend checking the official Nuxt Security module documentation or its repository for up-to-date options and usage instructions feat(nuxt): add initial CSP handling.

@kind canyon How should my CSP settings look like if I am using Nuxt-security in order to solve this CSP issue?
kind canyonBOT
Let me check the knowledge base for you again. One moment! :books:
I'm sorry, but the knowledge sources do not contain enough information to provide a definitive example of how your CSP settings should look when using the Nuxt Security module. While there is mention of CSP support being added to Nuxt and that the Nuxt Security module's configuration takes precedence, there are no concrete examples or documentation excerpts in the provided sources that show the exact syntax or options (such as a policies property) for configuring CSP within nuxt-security.
