CVE-2025-6895Network attack vector

Account takeover via unrestricted user-meta token lookup

Published Jul 26, 2025 · Updated Jul 28, 2025

Authentication bypass in Melapress Login Security 2.1.0 through 2.1.1 allows remote attackers to log in as an arbitrary user. The get_valid_user_based_on_token() function queries user metadata by a supplied value without restricting the lookup to the temporary-login token field. Exploitation is unauthenticated but requires knowledge of a stored user-meta value; success creates a session with that user's privileges.
