What is CVE-2026-4074?
CVE-2026-4074 is a medium-severity cross-site scripting vulnerability in karim42 Quran Live Multilanguage, published on 22 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
