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`)."}],"title":"WP-Optimize <= 4.5.0 - Missing Authorization to Authenticated (Subscriber+) Plugin Settings Update and Image Manipulation","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6a0a376e-ea3a-40ca-9341-f28f92e15e02?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/tags/4.4.1/includes/class-wp-optimize-heartbeat.php#L65"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/trunk/includes/class-wp-optimize-heartbeat.php#L65"},{"url":"https://plugins.trac.wordpress.org/browser/wp-optimize/tags/4.4.1/includes/class-wp-optimize-heartbeat.php#L82"},{"url":"https://research.cleantalk.org/cve-2026-2712/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-863 Incorrect Authorization","cweId":"CWE-863","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"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"}}],"credits":[{"lang":"en","type":"finder","value":"Dmitrii Ignatyev"}],"timeline":[{"time":"2026-03-03T12:42:09.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-04-09T11:52:37.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-10T13:46:09.364998Z","id":"CVE-2026-2712","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-10T13:46:16.718Z"}}]}}
