description

Relevanssi – A Better Search for WordPress is affected through version 4.28.3. An unauthenticated attacker may cause script to run in the browser of someone viewing affected content, but exploitation requires a non-empty "Allowable tags in excerpts" configuration with a relevant tag-name prefix.

mitigation

Upgrade to a release newer than 4.28.3 when available. Until then, clear the "Allowable tags in excerpts" setting to reduce exposure.
