CVE-2026-4074

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.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)

Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
