File Manager Integration Returning 403 Forbidden

[aohlrogge]

Using Laravel Backpack v7 with FileManager v4 when adding 'elfinderOptions' => [] to the field definition the "Insert image or file" button shows up in the toolbar but clicking on it results in a 403 Forbidden screen.

In the logs I see Someone attempted to tamper with mime types in elfinder popup. The attempt was blocked.

From debugging it seems that ckeditor isn't sending the required encrypted mimes string in the showPopup request.

CrawlChat Answer:

I apologize, but this specific issue regarding the 403 Forbidden error with FileManager v4 and the encrypted mime types string not being sent by CKEditor is not documented in the available Backpack resources.

This appears to be a specific integration issue between:

• Laravel Backpack v7
• FileManager v4 (elFinder)
• CKEditor field

What I can tell you is that the error message "Someone attempted to tamper with mime types in elfinder popup. The attempt was blocked" indicates a security check in FileManager that validates the mime types parameter is properly encrypted before allowing file operations.

To resolve this, I recommend:

1. Check the FileManager v4 documentation for changes in how it handles encrypted mime type strings with CKEditor
2. Verify your FileManager configuration in Backpack is correctly set up
3. Review the Backpack CKEditor field GitHub repository for known issues or updates
4. Contact Backpack support or the FileManager project with this specific error, as it involves their security validation logic

It would be better to reach out to the Backpack support team or file an issue on the GitHub repositories for both projects to get assistance with this integration issue.

The Filemanager integration with ckeditor had been broken for a few time, since ckeditor changed it's distribution model.

We currently don't have plans on working on an elfinder integration with ckeditor. To "soften" that burden, we made uploaders easy and you can use alternative fields with working uploaders like easyMDE or Summernote.

You are still completely free to publish the files to your project resource folders and work on that bit of integration part. If you do and are willing to share with the community, feel free to submit a PR and I can try to review and merge it 👍
