Privilege escalation in the MailOptin WordPress plugin (by properfraction) affects all versions up to and including 1.2.77.3, stemming from incorrect privilege assignment (CWE-266). An attacker can obtain elevated privileges within the WordPress site, potentially reaching administrator-level control that yields full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV; it was reported by Patchstack.
Stored Cross-Site Scripting in MailOptin WordPress plugin (versions ≤ 1.2.78.0) allows Contributor-level authenticated users to inject malicious JavaScript payloads that execute in the browser context of higher-privileged users - typically site administrators - when they view the affected content. The CVSS scope change (S:C) confirms the injected script escapes the contributor's own context, making this an effective privilege escalation vector in multi-author WordPress environments. No public exploit code or active exploitation has been identified at time of analysis.
