CVE-2026-111626 Details
Description
Webreaper Damselfly through 4.5.3 contains an authentication bypass vulnerability that allows unauthenticated attackers to access all /api/* routes because controller authorization attributes are commented out. Attackers can send PUT /api/users with Admin roles to create administrator accounts, or POST /api/users to reset any user's password, gaining full control.
A vulnerability in Webreaper Damselfly versions through 4.5.3 allows unauthenticated attackers to bypass authentication and access all API routes. This is due to the authorization attributes in the controllers being commented out. Exploitation of this vulnerability enables attackers to create administrator accounts by sending PUT requests to the API users endpoint with Admin roles, or to reset passwords of existing users, including administrators, thereby gaining full control over their accounts.
To address this vulnerability, re-enable the [Authorize] attribute on all API controllers, using the admin policy for user management. Additionally, set a fallback authorization policy that requires authenticated users, and add a startup test to ensure every API endpoint has an authorization policy.
