The search term site:pastebin.com + csp serves as a reminder that web security is a constant cat-and-mouse game. While Pastebin is a valuable resource for learning and sharing bypass techniques for educational purposes, it also highlights the fragility of poorly configured policies. For modern web applications, the goal should be to move away from the "allow-lists" often found in these pastes and toward a robust, nonce-based Strict CSP.
Searching Pastebin often reveals lists of these "dangerous" domains that are frequently whitelisted by mistake, such as: ://googleapis.com cdn.jsdelivr.net connect.facebook.net 4. Moving Toward Strict CSP
(most likely)
: Ensure your connect-src directive does not include Pastebin to prevent it from being used as a destination for stolen data. CSP Bypass (Low) can't be solved with pastebin anymore #382
: Pastebin now strictly serves raw pastes with Content-Type: text/plain and includes the x-content-type-options: nosniff header. site%3apastebin.com+csp
site:pastebin.com "Content-Security-Policy" "report-uri"
site:pastebin.com "csp" -"Content-Security" The search term site:pastebin
If your site's CSP ends up on Pastebin—perhaps because a developer shared a "broken" config for help—it provides a roadmap for attackers. It tells them exactly which domains you trust and, more importantly, which ones they can target to inject malicious code.
