CVE-2026-2487: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in weblizar Admin Custom Login
The Admin Custom Login plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.6.4 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.

Technical Summary
CVE-2026-2487 is a stored Cross-Site Scripting vulnerability in the Admin Custom Login WordPress plugin by Weblizar. The flaw arises from improper neutralization of input during web page generation, specifically in admin settings, allowing authenticated administrators to inject malicious scripts. This vulnerability affects all plugin versions up to and including 3.6.4 and is limited to multi-site WordPress installations or those with unfiltered_html disabled. The CVSS 3.1 base score is 4.4, indicating medium severity, with attack vector network, high attack complexity, requiring high privileges, no user interaction, and a scope change. The impact includes limited confidentiality and integrity loss but no availability impact.
Potential Impact
An authenticated user with administrator-level permissions can inject arbitrary web scripts into pages via the plugin's admin settings. These scripts execute when users access the injected pages, potentially leading to unauthorized actions or data exposure within the affected WordPress multi-site or restricted unfiltered_html environments. The impact is limited to confidentiality and integrity, with no availability impact reported.
Mitigation Recommendations
No official patch or fix has been confirmed as of the provided data. Users should check the vendor advisory for updates. Until a fix is available, restrict administrator access to trusted users only and consider disabling or replacing the plugin in multi-site or unfiltered_html-disabled environments to mitigate risk.
