CVE-2025-3603: CWE-620 Unverified Password Change in v1rustyle Flynax Bridge
The Flynax Bridge plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 2.2.0. This is due to the plugin not properly validating a user's identity prior to updating their details like password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.
AI Analysis
Technical Summary
CVE-2025-3603 is a critical vulnerability in the v1rustyle Flynax Bridge WordPress plugin (versions up to 2.2.0) caused by improper identity verification before allowing password changes. This weakness (CWE-620) permits unauthenticated attackers to change any user's password, including administrators, leading to privilege escalation and full account takeover. The vulnerability is remotely exploitable without user interaction and has a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). No patch or official fix has been documented yet, and the plugin is not a cloud service, so remediation depends on vendor updates.
Potential Impact
Successful exploitation allows unauthenticated attackers to reset passwords for arbitrary users, including administrators, resulting in complete account takeover. This compromises confidentiality, integrity, and availability of the affected WordPress site, potentially allowing full control over the site and its data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the WordPress installation and monitor for suspicious activity. Avoid using the vulnerable plugin version and consider disabling or removing the Flynax Bridge plugin if possible.
