CVE-2025-6221: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in luuptek Embed Bokun
The Embed Bokun plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘align’ parameter in all versions up to, and including, 0.23 due to insufficient input sanitization and output 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.
AI Analysis
Technical Summary
CVE-2025-6221 is a stored cross-site scripting vulnerability in the Embed Bokun plugin for WordPress, affecting all versions up to and including 0.23. The issue is due to improper neutralization of input in the 'align' parameter, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary web scripts. These scripts execute whenever a user accesses the injected page, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial confidentiality and integrity impact with no availability impact. There is no vendor advisory or patch link provided, and no known exploits have been reported.
Potential Impact
An attacker with Contributor-level or higher access can store malicious scripts via the 'align' parameter, which execute in the context of users viewing the affected pages. This can lead to partial confidentiality and integrity impacts such as theft of user data or session tokens. Availability is not impacted. The vulnerability requires authenticated access, limiting exposure to users with some level of trust on the site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider removing or disabling the Embed Bokun plugin if possible. Monitor for plugin updates from luuptek addressing this vulnerability.
