CVE-2026-92798
validatedZero produced an exploit or a check.GHSA-fc28-r9m2-c784 ↗EUVD-2026-103233 ↗
description
WordPress User Registration & Membership plugin versions through 5.2.8 can process attacker-supplied content as registered shortcodes. An unauthenticated attacker can trigger this on restricted pages whose restriction message includes the referrer-URL smart tag.
mitigation
Remove the referrer-URL smart tag from content-restriction messages and restrict access to affected pages until patched. Upgrade to a vendor-maintained release that remediates the issue after confirming the release notes.
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
