CVE-2026-86833: MetForm: Submitted values inject markup into notification emails

An unauthenticated form submitter can supply HTML in form-field values. The plugin inserts those values into administrator and submitter notification email bodies without sufficient sanitization or escaping, allowing attacker-chosen markup in mail sent by the site. This creates a phishing and content-spoofing primitive; browser JavaScript execution is not established by the description. The affected field names and mail-rendering function are undisclosed. Affected versions: < 4.3.1. The authoritative export identifies 4.3.1 as fixed for this CVE.
