open_basedir problem when inserting image in RTE

[wtfred]

Bug description
When inserting image in RTE, when saving content, we got a 503 error because of open_basedir restriction.
We are using Plesk default php settings with open_basedir set.
I don't know since when this problem exists, because it's on a website that is not so active. We updated it from TYPO 10 to 11 in may this year, and last update to 11.5.33 in november.

Steps to reproduce
To reproduce the problem:

1. Open content
2. Insert image
3. Validate "image properties" modale
4. Save content
5. Got 503 in TYPO3 backend

Screenshots or logs

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1476107295: PHP Warning: is_file(): open_basedir restriction in effect. File(/fileadmin/user_upload/subdirectory/Image.jpg) is not within the allowed path(s): (/var/www/vhosts/domain.com/:/tmp/) in /var/www/vhosts/domain.com/httpdocs/releases/20231116103330/public/typo3conf/ext/rte_ckeditor_image/Classes/Database/RteImagesDbHook.php line 141

Environment

• TYPO3 version: 11.5.33
• PHP version: 8.1.26
• Extension version: 11.0.14

==> Potential fix ?
Change line 136 in rte_ckeditor_image/Classes/Database/RteImagesDbHook.php to

$imageSource = trim($attribArray['src'] ?? '', '/ ');

in order to get rid of the initial /
