CVE-2026-81278 Aug 31, 20:40 MEDIUM This Month

Missing Authorization in the WPExperts Post SMTP WordPress plugin (versions 4.0.0 through beta.1) permits low-privilege authenticated users to perform settings changes that should be restricted to administrators. The flaw, rooted in CWE-862, means certain plugin actions lack adequate capability checks before execution, allowing role-inappropriate operations against the plugin's SMTP configuration. Impact is confined to integrity and availability - an attacker can alter mail server settings or disrupt outbound email delivery - with no confidentiality impact identified. No public exploit or CISA KEV listing has been identified at time of analysis.
