This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The generate_jqMathFormula() function directly concatenates the 'style' attribute value into an HTML style attribute without applying esc_attr() or any other escaping. 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."}], "title": "WM JqMath <= 1.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'style' Shortcode Attribute", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/b4aebb45-b47b-4b5a-8281-400a4b786689?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/wm-jqmath/trunk/wm_jqmath.php#L33"}, {"url": "https://plugins.trac.wordpress.org/browser/wm-jqmath/tags/1.3/wm_jqmath.php#L33"}, {"url": "https://plugins.trac.wordpress.org/browser/wm-jqmath/trunk/wm_jqmath.php#L27"}, {"url": "https://plugins.trac.wordpress.org/browser/wm-jqmath/tags/1.3/wm_jqmath.php#L27"}], "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": "Gilang Asra Bilhadi"}], "timeline": [{"time": "2026-04-14T19:46:51.000Z", "lang": "en", "value": "Disclosed"}]}}}
