I don't understand

so I work with a symlink on index.php

Really index.php? Shouldn't it be /images/

One of some more related issues (if we talk about /images/): #24959

On my Subdomains with cms 3.9.19 this syntax is working
system wide well, on cms 4.0.0-beta4-dev Nightly Builds 12 September 2020 02:01:10 UTC it's not working well!?
"symlink('/mnt/web101/...103/htdocs/ksv23000/images/', '/mnt/web101/...103/htdocs/ligatest/images');"

By the way, the JCE Filebrowser works well. The Joomla Mediamanger takes no result !?

Is this still a problem?

Closing due to no response with additional info.

Is this still a problem?

Yes, it is. Error throwing method Path::check has never been adapted to respect symlinks.

Joomla 4.1.5-dev, Joomla 4.1.4.

No issues with Joomla 3 sites with identical symlinks. Only Joomla 4.

Symlink from Joomla 4 folder:
/www/htdocs/abcd/joomla4/images/

Symlink to /www/htdocs/abcd/images-ghsvs-symlink-target/

Error:
Joomla\CMS\Filesystem\Path::check() - Snooping out of bounds @ /www/htdocs/abcd/images-ghsvs-symlink-target/

Could someone please reopen this issue?

Still an issue with J!4.2.5.

Is it possible to make the title of this issue more meaningful? Something like "[4] Media Manager fails with SymLinks" or so.

Thank you!

And could you please remove the Information Required label. Thx again.

Still an issue with J!4.3.2

This is a real issue whenever you use a symlink for your images folder. In one particular website, a symlink for the images folder is used to link to a NAS where multiple sites use the same storage.

So I looked to see if there is a quick fix related to the symlinks but not that I can see. The particular block in the Path::check function has been in place since at least 28 May 2009.

This was not a problem in Joomla 3 because that function is never called, however the Local Adapter plugin calls it many times. The code is a bit misleading because it calls the function getLocalPath() but all this does is call the Path::check() function.

A quick fix here would be to strip out the Path::check() function and simply return the rootPath and provided path until symlink support is added to the Path::check() function.

Would be nice if this was fixed!!!!

Modded the following file:

/webdata/joomla/v009/libraries/src/Filesystem/Path.php

Commenteded out the following starting around line #171.

        $path = self::clean($path);
/*
        if ((JPATH_ROOT != '') && strpos($path, self::clean(JPATH_ROOT)) !== 0) {
            throw new \Exception(
                sprintf(
                    '%1$s() - Snooping out of bounds @ %2$s',
                    __METHOD__,
                    self::removeRoot($path)
                )
            );
        }
*/
        return $path;

Seems to have worked but still testing
