pyLoad is a free and open-source download manager written in Python. Prior to version 0.5.0b3.dev97, a Host Header Spoofing vulnerability in the @local_check decorator allows unauthenticated external attackers to bypass local-only restrictions. This grants access to the Click'N'Load API endpoints, enabling attackers to remotely queue arbitrary downloads, leading to Server-Side Request Forgery (SSRF) and Denial of Service (DoS). This issue has been patched in version 0.5.0b3.dev97.

CVE-2026-33314 [MEDIUM] CWE-287 Improper Authentication and Origin Validation Error in pyload-ng
Improper Authentication and Origin Validation Error in pyload-ng
### Summary
A Host Header Spoofing vulnerability in the `@local_check` decorator allows unauthenticated external attackers to bypass local-only restrictions. This grants access to the Click'N'Load API endpoints, enabling attackers to remotely queue arbitrary downloads, leading to Server-Side Request Forgery (SSRF) and Denial of Service (DoS).
### Details
The `pyload` WebUI provides an API for the Click'N'Load plugin, which is intended to be accessed only from the local machine (e.g., via a browser extension sending requests to `localhost:9666`). To enforce this, the `pyload` application uses a `@local_check` decorator on the relevant routes in `src/pyload/webui/app/blueprints/cnl_blueprint.py`.
However, the `@local_check
