AI Summary: This issue proposes a security enhancement for the default web server configuration. Currently, it binds to all network interfaces (0.0.0.0), which can unintentionally expose the web UI to the network. The suggested solution is to change the default to localhost (127.0.0.1) for increased security, requiring explicit configuration for external access and adding warnings for users who choose to bind to all interfaces.

AI Summary: This issue identifies a security vulnerability in FastAPI POST endpoints where CSRF tokens are not validated. This allows for Cross-Site Request Forgery attacks, enabling malicious sites to trigger actions like restarting cameras or reloading configurations on behalf of authenticated users. The suggested solution involves implementing CSRF token generation and validation, requiring an `X-CSRF-Token` header, or utilizing a SameSite cookie policy.

AI Summary: This issue describes a security vulnerability where bearer token validation in `web_server.py` is susceptible to timing attacks due to the use of the `!=` operator. An attacker could potentially brute-force tokens by measuring response times. The suggested solution is to replace the `!=` comparison with `secrets.compare_digest()` for constant-time comparison.

AI Summary: This issue describes a potential security vulnerability in the clips serving endpoint where unsanitized user-provided filenames could lead to directory traversal attacks. Attackers might exploit this to access sensitive files on the system. The suggested solution involves robust path validation, including stripping directory components and verifying the resolved path remains within the designated clips directory.

AI Summary: The motion filter currently reinitializes its background subtractor every time its parameters are updated, leading to significant performance degradation and false positives as it relearns the background. The proposed solution is to selectively reinitialize the background subtractor only when critical parameters like 'history' change, while allowing other parameters to be updated dynamically.
