description

Fancy Comments WordPress versions through 1.2.21 are affected by reflected cross-site scripting. An unauthenticated attacker may cause script to run in a victim’s browser if the victim interacts with attacker-supplied content.

mitigation

Disable the fancy-facebook-comments plugin until a remediated release is available. Remove it where it is not required and monitor the vendor’s updates for a fixed version.
