CVE-2026-111661
waynboot-mall through 2.0.0 contains a missing authentication vulnerability that allows unauthenticated attackers to send arbitrary email by calling the anonymously mapped /callback/email endpoint.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
