A Bug in the template system

Reported by: asfarfordev's profile asfarfordev Owned by:
Milestone: Priority: normal
Severity: normal Version: 6.2
Component: Upgrade/Install Keywords:
Focuses: administration, template Cc:


I think there is a serious vulnerability in the theme system in WordPress that can be used against any site.
I was developing a WordPress theme called Apex, and this morning I was surprised that all the files I developed had changed.
I searched and found that the problem is that there is a theme called Apex in the theme market: it updates automatically.
Therefore, it is possible to use this exploit by any other programmer, such as creating a theme called hespres and placing it in the store to update the theme of the hespres website if the automatic update is enabled.

Hello @asfarfordev and welcome to Trac.

I guess you missed the statement on top of the new ticket form "Do not report potential security vulnerabilities here."

Generally, if developing a theme, be careful when use a theme slug that in use on the repo, but prefix it to something like "asfarfordev-apex". And do not turn on automatic updates for self developed themes.

Or, better, add an "Update URI" ( theme header that does not point to
