| Title | alexta69 MeTube 2026.04.09 Permissive Cross-domain Policy with Untrusted Domains |
|---|
| Description | MeTube unconditionally reflects the Origin header in CORS responses and has no authentication, allowing any malicious website to initiate downloads, delete files, overwrite cookies, and manage subscriptions on a victim's instance via cross-origin requests. I've made a pull request with the fixed code. https://github.com/alexta69/metube/pull/949
