Possible upgrage to wrong theme/plugin

Upgrade can be done to wrong theme, if theme with that same name is listed in WP repository.


  • I have created 'Twenty Fifteen' theme, version 0.9 (for personal use)
  • Month later WP team release in WP repository new 'Twenty Fifteen' theme, version 1.0
  • WP Upgrader receive information that there is available update for my theme
  • On upgrade my theme is overriden with the WP one

This 'security hole' can be used by some theme/plugin authors, to create equivalents of commercial products that will get overridden on next upgrade.

Possible solution:

WP API could check some additional param (like Author) before returning results about available update.

(sidenote) I could add a filter to my theme, to exclude it from checking it in WP API, but it will only work when my theme is active.
