CVE-2021-25111

31
FAUCET Score

CVE-2021-25111 is an open redirect vulnerability affecting the English WordPress Admin plugin prior to version 1.5.2. This medium-severity flaw (CVSS 6.1) allows attackers to redirect users to arbitrary malicious sites due to insufficient validation of the admin_custom_language_return_url parameter. While not actively exploited (no KEV entry) and lacking public exploit code beyond a Nuclei template, its low attack complexity and user interaction requirement pose a risk of phishing or credential theft. Community and media attention for this CVE are minimal.
