Patches

The problem has not been patched yet. Users should upgrade to patched versions once they become available. Currently affected versions are:

  • 2.6.4
  • 2.5.20

Alternatively, configuring a Web Application Firewall (WAF) to filter potentially malicious input could serve as a temporary mitigation.
