PHP vulnerabilities

As reported earlier regarding the two critical vulnerabilities in PHP, none of the TOPdesk product uses PHP. These vulnerabilities therefore do not affect the TOPdesk application, and no action is required for your environment.

Some of our external websites do employ PHP however. Therefore, we've decided to temporarily take the following websites offline, until the fix is implemented:

- www.topdesk.com
- careers.topdesk.com
- marketplace.topdesk.com

Your my.topdesk access will remain unaffected.

If your organization uses PHP in other applications or custom integrations, please follow the PHP security guidance for those systems.
