The display_admin_ajax() method does not call checkForCap() (which requires unfiltered_html capability), and several controller actions only validate the nonce (validateToken()) without calling validatePermission(). This makes it possible for authenticated attackers, with Contributor-level access and above, to enumerate slider metadata and create, modify, and delete image storage records by obtaining the nextend_nonce exposed on post editor pages."}],"title":"Smart Slider 3 <= 3.5.1.33 - Missing Authorization to Authenticated (Contributor+) Slider Data Read and Image Record Manipulation","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/53a08b59-b7e0-419a-bfc3-528bcddb1ac2?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/smart-slider-3/tags/3.5.1.32/Nextend/SmartSlider3/Platform/WordPress/Admin/AdminHelper.php#L155"},{"url":"https://plugins.trac.wordpress.org/browser/smart-slider-3/trunk/Nextend/SmartSlider3/Platform/WordPress/Admin/AdminHelper.php#L155"},{"url":"https://plugins.trac.wordpress.org/browser/smart-slider-3/tags/3.5.1.32/Nextend/SmartSlider3/Application/Admin/Sliders/ControllerAjaxSliders.php#L26"},{"url":"https://plugins.trac.wordpress.org/browser/smart-slider-3/tags/3.5.1.32/Nextend/Framework/Image/ControllerAjaxImage.php#L37"},{"url":"https://plugins.trac.wordpress.org/browser/smart-slider-3/tags/3.5.1.32/Nextend/SmartSlider3/Platform/WordPress/HelperTinyMCE.php#L30"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3489689%40smart-slider-3%2Ftrunk&old=3439582%40smart-slider-3%2Ftrunk&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"darkestmode"}],"timeline":[{"time":"2026-03-12T17:56:45.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-04-07T08:51:34.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-08T14:29:43.699842Z","id":"CVE-2026-4065","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":"2026-04-08T14:29:55.319Z"}}]}}
