CVE-2025-12016: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in muniyandibg qnotsquiz
The qnotsquiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'qnotsquiz_custom_start_text' parameter in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AI Analysis
Technical Summary
CVE-2025-12016 is a stored cross-site scripting vulnerability in the qnotsquiz WordPress plugin (versions up to 1.0.0). The issue is due to improper neutralization of input in the 'qnotsquiz_custom_start_text' parameter, allowing authenticated administrators to inject arbitrary scripts. This affects multi-site WordPress installations or those with unfiltered_html disabled. The vulnerability requires high privileges and does not involve user interaction to trigger once the malicious content is stored and viewed.
Potential Impact
An authenticated attacker with administrator-level access can inject malicious scripts that execute in the context of users visiting the affected pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. The vulnerability does not affect availability and requires high privileges to exploit.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is released, restrict administrator access to trusted users only and consider disabling or removing the qnotsquiz plugin on multi-site installations or sites with unfiltered_html disabled if feasible.
