+title: Password Pusher Allows Session Token Interception Leading
+  to Potential Hijacking
+date: 2024-12-30
+description: |
+  ### Impact
+
+  A vulnerability has been reported in Password Pusher where an
+  attacker can copy the session cookie before a user logs out,
+  potentially allowing session hijacking.
+
+  Although the session token is replaced and invalidated upon logout,
+  if an attacker manages to capture the session cookie before this
+  process, they can use the token to gain unauthorized access to the
+  user's session until the token expires or is manually cleared.
+
+  This vulnerability hinges on the attacker's ability to access the
+  session cookie during an active session, either through a
+  man-in-the-middle attack, by exploiting another vulnerability like
+  XSS, or via direct access to the victim's device.
+
+  ### Patches
+
+  Although there is no direct resolution to this vulnerability, it is
+  recommended to always use the latest version of Password Pusher to
+  best mitigate risk.
+
+  ### Workarounds
+
+  If self-hosting, ensure Password Pusher is hosted exclusively over
+  SSL connections to encrypt traffic and prevent session cookies from
+  being intercepted in transit. Additionally, implement best practices
+  in local security to safeguard user systems, browsers, and data
+  against unauthorized access.
+
+  To further mitigate session hijacking risks, Password Pusher
+  implements the following security measures:
+
+  1. **Automatic Session Expiration**: Sessions are automatically
+     expired after 2 hours of inactivity, reducing the window for
+     potential exploitation.
+
+  2. **Session Reset on Login and Logout**: Sessions are fully reset
+     both when a user logs in and logs out, ensuring that session
+     tokens are not reusable post-logout. This practice invalidates
+     old session tokens and issues new ones, minimizing the risk of
+     session hijacking.
+
+  3. **Encrypted Cookies**: Cookies are encrypted using the value of
+     SECRET_KEY_BASE from the application's configuration. This
+     encryption adds a layer of protection against tampering or reading
+     the session cookie's contents if intercepted, although it doesn't
+     prevent the cookie from being used if stolen.
+
+  **Note**: While these measures significantly enhance security, they
+  are part of a broader security strategy.
