Detailsinfo

A vulnerability, which was classified as problematic, was found in itsananderson Short Comment Filter Plugin up to 2.2 on WordPress. This affects an unknown code block. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

The Short Comment Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Minimum Count' settings field in all versions up to and including 2.2. This is due to insufficient input sanitization (no sanitize callback on register_setting) and missing output escaping (no esc_attr() on the echoed value in the input's value attribute). The option value is stored via update_option() and rendered unescaped in an HTML attribute context. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in the settings page that will execute whenever a user accesses that page. This is particularly impactful in WordPress multisite installations or when DISALLOW_UNFILTERED_HTML is set, where administrators are not granted the unfiltered_html capability.

The weakness was disclosed by Muhammad Nur Ibnu Hubab. The advisory is shared at wordfence.com. This vulnerability is uniquely identified as CVE-2026-3362 since 02/27/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Additional levels of successful authentication are required for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.
