Sensiolab do not maintain this composer librairies and if you used to analyze the security composer library, it can create an error inside your application
Please remove this librairie by this command,
composer remove sensiolabs/security-checker
You can also remove the dashboard located in
includes/ClicShopping/Apps/Tools/SecurityCheck/Modules/ClicShoppingAdmin/Dashboard/ComposerVulnerabilities
A new ClicShopping version is on the waway
