CVE-2026-93889
validatedZero produced an exploit or a check.GHSA-7wqp-vpcj-332m ↗EUVD-2026-91957 ↗
description
WP Mail Catcher versions through 2.1.12 can retain untrusted mail-error content that runs as script when affected content is viewed. An unauthenticated attacker needs a separately installed plugin that passes user-controlled values into mail fields involved in a delivery failure.
mitigation
Disable or remove WP Mail Catcher until a vendor-fixed release is available. Also restrict or disable unauthenticated form submissions from plugins that can supply user-controlled mail fields.
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
