CVE-2025-11806: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in qzzr Qzzr Shortcode Plugin
The Qzzr Shortcode Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'qzzr' shortcode in all versions up to, and including, 1.0.1. This is due to insufficient input sanitization and output escaping on the 'quiz' attribute. 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-2025-11806 is a stored cross-site scripting vulnerability in the Qzzr Shortcode Plugin for WordPress, affecting all versions up to 1.0.1. The issue is due to improper neutralization of input in the 'quiz' attribute of the 'qzzr' shortcode, allowing authenticated users with contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of any user accessing the injected page, potentially compromising confidentiality and integrity. The vulnerability is classified under CWE-79 and 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). No known exploits in the wild have been reported, and no patch or official remediation has been provided in the available information.
Potential Impact
An attacker with contributor-level or higher access can inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to partial confidentiality and integrity loss, such as theft of session tokens or unauthorized actions performed on behalf of users. There is no impact on availability reported. The vulnerability affects all versions of the plugin up to and including 1.0.1.
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 disabling or removing the Qzzr Shortcode Plugin if possible to prevent exploitation.
