This is due to insufficient input sanitization and output escaping in the vc_raw_html::render() method, which base64-decodes shortcode content (after a strip_tags() that is bypassed because the encoded payload contains no tags on save) and concatenates the result directly into the page HTML. Because WordPress's save-time wp_kses_post() filter only sees the inert base64 text inside a normal shortcode bracket and does not decode it, the dangerous tags survive into post_content and are emitted unescaped at render time. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page (for example, when an Editor or Administrator previews the pending post)."}], "title": "tagDiv Composer <= 5.4.5 - Authenticated (Contributor+) Stored Cross-Site Scripting", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/48ae6e52-4a66-4676-9528-6f997ef54c7a?source=cve"}, {"url": "https://tagdiv.com/tagdiv-composer-page-builder-basics/"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Truoc Phan"}], "timeline": [{"time": "2026-08-24T15:27:36.000Z", "lang": "en", "value": "Disclosed"}]}}}
