Overriding core Joomla! controller

[olivier1000]

Hello, fellow Joomla users.

First and foremost, please acknowledge that upgrading to Joomla! 4 or 5 is not an option for my situation. I need this to be done in Joomla 3.10.10.

I want to override the core Joomla UsersController located in components\com_users\controller.php. I need to change the code it contains.
There seems to be no documentation on the matter, and the only plausible solution to what I'm trying to achieve, namely creating a code folder in the template I'm using, does not work.

Is there a way to override a controller's code without risk of it being overwritten by a Joomla update ?

There will be no more updates for Joomla 3.10.x - it's obsolete and EOL, unless you're subscribed to the Extended Long term support. (https://elts.joomla.org/)

J4/j5 are the only supported Joomla CMS.

First and foremost J3 has a major vulnerability https://developer.joomla.org/security-c ... ables.html
You can pay for extra support or try https://github.com/TLWebdesign/Joomla-3 ... per-hotfix

@webdongle that can only be exploited in some very specific (and unusual) scenarios all of which require an element of "hack yourself"

@olivier1000 No Is there a way to override a controller's code without risk of it being overwritten by a Joomla update. Hence no documentation explaining how to do it

Sorry I must have misunderstood https://nvd.nist.gov/vuln/detail/CVE-2023-40626 where it says Severity base level 7.5 high
mea culpa

The severity is high but the exploitability is low
