Keypoints
- Attackers can generate malicious links that appear legitimate using Firebase Dynamic Links.
- Google introduced an Allowed Domains feature to limit redirection but does not fully prevent metadata abuse.
- Malicious actors can craft links with fake metadata to deceive users into trusting the domain.
- Links created via APIs are not visible in the Firebase console, making detection difficult.
- Domain owners should monitor their allowed domains, educate users, and seek support to mitigate risks.
