CVE-2026-118495 · Severity: info · Published 2026-11-12

AcyMailing is an email marketing platform for WordPress and Joomla that manages subscriber lists and campaigns. An unauthenticated attacker who knows a subscriber's email address can retrieve sensitive subscriber data, including a secret key used to authorize subscription management actions. With this key, an attacker can impersonate the subscriber to trigger account deletion or data export requests.
