Restrict Attachments Based on File Type

What do people do to restrict .bmp uploads? :) no matter how big a font in how-tos I use - people still ignore. I also would like to restrict .exe uploads.

I know of https://jira.atlassian.com/browse/CONF-6931 but it had not seen much progress...

I would not want to do it completely right - looking into the file, understanding it's format; just a basic extension filter would work for most abusers. thanks!

Have a look at overriding the 'attachfile' action

 <action name="attachfile" class="com.atlassian.confluence.pages.actions.AttachFileAction">

You can do this via the conveyor plugin

Hi errno,

You can use this add-on to restrict attachment based on file types https://marketplace.atlassian.com/plugins/com.elitesoftsp.confluence.attachment.tool.plugins/server/overview

It works well with my system.

You can implement this as a servlet filter module in a plugin which intercepts all multipart requests and allows or denies them based on the filename in the request.

I'd look at the AttachFileAction in the Confluence source code as an example of how to handle multipart requests.

Overriding the actions in Confluence as Colin suggests is probably not a great idea. His example there only covers some of the ways in which attachments are added to Confluence.

Hi Matt,

I want to write a plugin that prevents users to update attachments in Confluence. The only way I see is to check during the file upload if an attachment with the same name aleady exists. If yes the request should be canceled (ideally with a note for the user) or the file should be renamed. If I understand you correctly, this should also be possible with a servlet filter module. I read the description, but I am not sure how to identify upload requests. Can you provide some help?
