CVE-2026-3353: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in intermod Comment SPAM Wiper
The Comment SPAM Wiper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'API Key' setting in all versions up to, and including, 1.2.1. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, 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-2026-3353 is a stored cross-site scripting vulnerability in the Comment SPAM Wiper WordPress plugin (up to version 1.2.1). It occurs due to improper neutralization of input in the 'API Key' setting, enabling authenticated users with administrator privileges to inject arbitrary web scripts. This affects multi-site WordPress installations or those with unfiltered_html disabled. The vulnerability requires high privileges and has a medium CVSS score of 4.4, reflecting limited attack complexity and impact confined to confidentiality and integrity.
Potential Impact
An authenticated attacker with administrator-level access can inject malicious scripts that execute in the context of users visiting affected pages, potentially leading to session hijacking or unauthorized actions. The impact is limited to confidentiality and integrity with no availability impact. This vulnerability only affects multi-site installations or those with unfiltered_html disabled, reducing the scope of affected environments.
Mitigation Recommendations
No official patch or fix is currently documented. Users should monitor the vendor's advisory for updates. Until a fix is available, restrict administrator access to trusted users only and consider disabling or removing the plugin in multi-site or unfiltered_html-disabled environments to avoid exploitation.
