### Summary An authentication bypass vulnerability exists due to improper trust in client-controlled cookies. The application accepts user-supplied cookie values containing a username and password-hash-derived value as sufficient authentication material. These cookies can be set or modified prior to login, allowing an unauthenticated attacker to impersonate arbitrary users without knowledge of the plaintext password. This issue stems from the absence of server-side validation of authentication state and reliance on attacker-controlled cookie data ### Details The vulnerability arises because the application accepts the client-supplied cookies named `meye_password_hash` and `meye_username` as sufficient authentication material. The server does not validate these values against a server-side session or enforce proper authentication checks before establishing an authenticated state. As a result, an unauthenticated attacker can set or modify these cookies to impersonate another user if the target username and corresponding hash are known. These cookies normally appear after using the "switch user" functionality; however, they can be added manually prior to authentication using standar
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.

- Customer inventory, deployment, reachability and exploitation have not been inspected.
