Simple Custom Login Page
Monthly
Stored Cross-Site Scripting in the Simple Custom Login Page WordPress plugin (versions ≤ 1.0.3) allows authenticated administrators to inject arbitrary CSS rules into wp-login.php, which is then rendered for every unauthenticated visitor to the login page. The changed scope (S:C in CVSS) is the critical risk amplifier: a single administrator-level compromise or malicious admin can silently overlay phishing UI elements on the WordPress login page, harvesting credentials from any user who subsequently visits. No public exploit code has been identified at time of analysis and this vulnerability is not listed in the CISA KEV catalog.
