What is CVE-2025-54809?

F5 Access for Android prior to version 3.1.2 is vulnerable to an identity verification bypass. The application, which utilizes HTTPS, fails to properly verify the identity of the remote endpoint, posing a significant risk of man-in-the-middle attacks. This could allow malicious actors to impersonate legitimate servers, intercept sensitive information, and compromise user data integrity. Users are strongly advised to upgrade to the latest version to mitigate this risk.
