CVE-2026-102173
validatedZero produced an exploit or a check.description
Kirki – Freeform Page Builder, Website Builder & Customizer through version 6.3.1 can store attacker-controlled script content in registration metadata. An unauthenticated attacker may cause script execution for people who view an affected published page when public user registration is enabled and the page renders the relevant user collection.
mitigation
Disable public user registration and unpublish or reconfigure Kirki pages that render user collections from registration metadata. Update to a vendor-fixed release when one is published; no fixed version is recorded in the advisory.
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
