CVE-2026-2487

Name of the Vulnerable Software and Affected Versions Admin Custom Login versions prior to 3.6.5

Description Stored Cross-Site Scripting occurs due to insufficient input sanitization and output escaping within the admin settings. This allows authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts execute when a user accesses the affected page. This issue specifically impacts multi-site installations and environments where unfiltered html has been disabled.

Recommendations Update Admin Custom Login to version 3.6.5 or later.
