This is due to the `nbu_crop_image` AJAX handler accepting a user-supplied `url` parameter that `Nbdesigner_IO::convert_url_to_path()` concatenates onto the uploads base directory without normalizing or stripping `../` sequences, and then deriving both the output directory and output file extension via `pathinfo()` from the same attacker-controlled path — with no `stripImage()` call before `writeImage()` is invoked. This makes it possible for unauthenticated attackers to write attacker-controlled PHP content to arbitrary locations outside the uploads directory, resulting in remote code execution when the written file is subsequently requested. This vulnerability is only exploitable when the `nbdesigner_upload_popup_style` site option is set to `a` (Advanced Upload Popup), which causes the handler to be registered for unauthenticated requests; however, the required `save-design` nonce is printed on the fully public frontend `upload-design-file` page, making it trivially obtainable by any anonymous visitor once that configuration is active."}],"title":"Printcart Store <= 2.13.2 - Unauthenticated Arbitrary File Upload via nbu_crop_image 'url' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2525ed97-b701-4f95-8d8c-202e816723c5?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/printcart-integration/tags/2.8.4/includes/class.advanced.upload.php#L284"},{"url":"https://plugins.trac.wordpress.org/browser/printcart-integration/tags/2.8.4/includes/class.advanced.upload.php#L272"},{"url":"https://plugins.trac.wordpress.org/browser/printcart-integration/tags/2.8.4/includes/class-util.php#L165"},{"url":"https://plugins.trac.wordpress.org/browser/printcart-integration/tags/2.8.4/includes/class.advanced.upload.php#L56"},{"url":"https://plugins.trac.wordpress.org/browser/printcart-integration/tags/2.8.4/includes/class-util.php#L586"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3747660%40printcart-integration&new=3747660%40printcart-integration"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-94 Improper Control of Generation of Code","cweId":"CWE-94","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"nudien"}],"timeline":[{"time":"2026-11-06T15:17:27.000Z","lang":"en","value":"Disclosed"}]}}}
