CVE-2025-12025: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in mahabubs YouTube Subscribe
The YouTube Subscribe plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions 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
The YouTube Subscribe WordPress plugin by mahabubs contains a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated administrators can inject arbitrary scripts via the plugin's admin settings, which are then stored and executed in the context of users visiting the injected pages. This vulnerability affects all plugin versions up to 3.0.0 and is limited to multi-site installations or sites with unfiltered_html disabled. The attack vector requires network access and high privileges, with no user interaction needed once the script is injected. The CVSS 3.1 base score is 4.4 (AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N).
Potential Impact
An attacker with administrator-level access can exploit this vulnerability to execute arbitrary scripts in the context of other users visiting the affected pages, potentially leading to limited confidentiality and integrity impacts. The vulnerability does not affect availability. Because exploitation requires high privileges and affects multi-site or restricted HTML capability environments, the overall impact is moderate.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Administrators should restrict access to the plugin's admin settings to trusted users only. Since the vulnerability requires administrator privileges and affects specific WordPress configurations (multi-site or unfiltered_html disabled), limiting administrative access and monitoring plugin usage is advised. Check the vendor's advisory or plugin updates regularly for any forthcoming official fixes.
