This is due to missing authorization on the handler combined with unsanitized array keys being passed to extract() inside tutor_load_template(), allowing attacker-controlled POST data to overwrite the local $template variable and, in the resulting templates/single-content-loader.php template, the $method_map and $context variables invoked at $method_map[$context](). This makes it possible for unauthenticated attackers to call an arbitrary zero-argument PHP function server-side and, via WordPress core edit_user(), to create a persistent subscriber-level account from request parameters."}],"title":"Tutor LMS <= 4.0.5 - Unauthenticated Remote Code Execution via 'template' and 'data' POST Parameters","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/65f68a49-8ded-479f-a9c3-187703bfae65?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/templates/single-content-loader.php#L71"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/templates/single-content-loader.php#L30"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/includes/tutor-template-functions.php#L118"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/includes/tutor-template-functions.php#L128"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/classes/Course_Filter.php#L224"},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.1/classes/Course_Filter.php#L58"},{"url":"https://plugins.trac.wordpress.org/changeset/3653079/tutor/trunk/templates/single-content-loader.php"},{"url":"https://plugins.trac.wordpress.org/changeset?old_path=%2Ftutor/tags/4.0.5&new_path=%2Ftutor/tags/4.0.6"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-74 Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')","cweId":"CWE-74","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Slopothecary"}],"timeline":[{"time":"2026-07-23T14:11:44.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-27T15:34:39.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-28T15:20:46.302387Z","id":"CVE-2026-16759","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"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":"2026-08-28T15:22:17.595Z"}}]}}
