CVE-2026-2281: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in edersonpeka Private Comment
The Private Comment plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Label text' setting in all versions up to, and including, 0.0.4. This is due to insufficient input sanitization and output escaping on the plugin's label text option. 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-2026-2281 is a stored cross-site scripting vulnerability in the edersonpeka Private Comment WordPress plugin, affecting all versions up to 0.0.4. The issue stems from improper neutralization of input in the 'Label text' option, enabling authenticated users with administrator privileges on multi-site WordPress installations (where unfiltered_html is disabled) to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to limited confidentiality and integrity impacts. The vulnerability has a CVSS 3.1 base score of 4.4, reflecting medium severity with network attack vector, high attack complexity, and no user interaction required.
Potential Impact
An authenticated attacker with administrator-level access on affected multi-site WordPress installations can inject malicious scripts via the 'Label text' setting. This can lead to execution of arbitrary scripts in users' browsers when they visit the injected pages, potentially compromising confidentiality and integrity of user interactions within the site. Availability is not impacted. The scope is changed due to the vulnerability affecting multiple components within the multi-site environment.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Administrators should limit administrator-level access to trusted users and consider disabling or avoiding use of the Private Comment plugin on multi-site installations where unfiltered_html is disabled until a fix is released. Monitor the vendor's advisory channels for updates regarding remediation.
