We cannot know what applications and Web sites Haringey Council uses. If you are asking about WinSCP: WinSCP is a client application developed in C++. It has nothing to do with PHP.
Organisations are aware of the current news regarding the announced PHP Vulnerability.
Please can you confirm if you have been impacted by this, what plans are in place to remediate. Or provide a statement (if not already published) with details/assurances regarding the reported current PHP vulnerability implications, for any of the applications and Web sites that Haringey Council currently use.
Thank you.
