Where can I report a site security issue?
By a site security issue or security vulnerability, we mean things like hacks or exploits on YouTube, but NOT things like user harassment or other violations of our Terms of Service.
If you think you've found a security issue or vulnerability on the YouTube site, please tell us about it here. We need to know the exact URL of a sample page, if possible, and we'd appreciate it if you could include a detailed description of the issue. Please use an email address where we can reach you if we need more information.
