Insufficient Verification of Data Authenticity vulnerability in WP ManageNinja LLC FluentAuth allows Identity Spoofing.
This issue affects FluentAuth: from n/a through 2.1.2.
AnalysisAI
Unauthenticated remote attackers can spoof identities and potentially take over accounts on WordPress sites running the FluentAuth (fluent-security) plugin through version 2.1.2 due to insufficient verification of data authenticity (CWE-345).
