CVE-2025-6681: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in delower186 Fan Page
The Fan Page plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘width’ parameter in all versions up to, and including, 1.0.1 due to insufficient input sanitization and output escaping. 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
The Fan Page plugin for WordPress (delower186) contains a stored cross-site scripting vulnerability (CWE-79) via the 'width' parameter in all versions up to 1.0.1. Authenticated users with Contributor-level privileges or higher can inject arbitrary web scripts due to improper input neutralization and output escaping. These scripts execute in the context of any user visiting the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability 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), reflecting network attack vector, low complexity, required privileges, no user interaction, and partial confidentiality and integrity impact. No patch or vendor advisory is currently provided.
Potential Impact
An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the 'width' parameter. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not impact availability. No known active exploitation has been reported.
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 removing or disabling the Fan Page plugin if feasible. Monitor for updates from the vendor delower186 regarding patches or official mitigations.
