This is due to insufficient file type validation detecting SVG files, allowing double extension files to bypass sanitization while being accepted as a valid SVG file. This makes it possible for authenticated attackers, with author level access and above, to upload arbitrary files on the affected site’s server which may make remote code execution possible.”,”published”:”2025-11-11T11:03:46.642Z”,”modified”:”2025-11-11T11:03:46.642Z”,”type”:”cve”,”title”:”Blocksy Companion \\u003c= 2.1.19 – Authenticated (Author+) Arbitrary File Upload via SVG Upload Bypass”,”source”:”Wordfence”,”references”:”https:\/\/www.wordfence.com\/threat-intel\/vulnerabilities\/id\/f8615422-5db7-495d-9956-7d6f658f42bf?source=cve\\nhttps:\/\/plugins.trac.wordpress.org\/changeset\/3391933\/blocksy-companion\/trunk\/framework\/features\/svg.php”,”id”:”CVE-2025-12846″,”bulletinFamily”:””,”cwe”:[“CWE-434″],”cvelist”:null,”sourceData”:”creativethemeshq Blocksy Companion *”,”sourceHref”:””,”cvss”:{“score”:8.8,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:L\/UI:N\/S:U\/C:H\/I:H\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Blocksy Companion”,”version”:”*”,”vendor”:”creativethemeshq”,”ai_description”:”Authenticated arbitrary file upload vulnerability in Blocksy Companion plugin for WordPress due to insufficient file type validation, allowing remote code execution”,”ai_severity”:”High”,”ai_vendor”:”Creative Theme HQ”,”ai_product”:”Blocksy Companion”,”ai_version”:”2.1.19 and below”,”ai_score”:8.8}<\/p>\n","protected":false},"excerpt":{"rendered":"
