What to do now
- There is no fixed version yet. If you can manage without Image Slider for now, deactivate and delete it until the developer ships a fix.
- If you must keep it, cut down who can log in (remove unused accounts, especially low-level ones, and turn off open registration) and put a web application firewall in front of the site.
- Check the Image Slider page for a fix; it updates when the CVE feeds do.
- Not sure which version you run? Check your version against every known Image Slider issue.
