This is due to the Heartbeat handler directly invoking `Updraft_Smush_Manager_Commands` methods without verifying user capabilities, nonce tokens, or the allowed commands whitelist that the normal AJAX handler (`updraft_smush_ajax`) enforces. This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke admin-only Smush operations including reading log files (`get_smush_logs`), deleting all backup images (`clean_all_backup_images`), triggering bulk image processing (`process_bulk_smush`), and modifying Smush options (`update_smush_options`)."}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","baseScore":5.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":2.5}]},"weaknesses":[{"source":"security@wordfence.com","type":"Primary","description":[{"lang":"en","value":"CWE-863"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/tags/4.4.1/includes/class-wp-optimize-heartbeat.php#L65","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/tags/4.4.1/includes/class-wp-optimize-heartbeat.php#L82","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/trunk/includes/class-wp-optimize-heartbeat.php#L65","source":"security@wordfence.com"},{"url":"https://research.cleantalk.org/cve-2026-2712/","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6a0a376e-ea3a-40ca-9341-f28f92e15e02?source=cve","source":"security@wordfence.com"}]}}]}
