| Título | Rowboat Labs Rowboat 0.1.67 Authentication Bypass Issues |
|---|
| Descrição |
A critical vulnerability has been identified in Rowboat (version v0.1.67 and prior) within the experimental 'tools_webhook' component. The issue is classified as a JWT "None" Algorithm Attack, which leads to a complete Authentication Bypass (CWE-347/CWE-287).
The vulnerability exists in the Flask-based 'app.py' located in 'apps/experimental/tools_webhook/'. The application's JWT decoding logic fails to enforce a specific cryptographic algorithm. Instead, it respects the "alg" header provided by the client. By supplying a JWT with the "alg" set to "none", an attacker can bypass the signature verification process entirely.
This allows a remote, unauthenticated attacker to craft and submit forged tokens via the 'X-Tools-JWE' header to the '/tool_call' endpoint. By manipulating the "sub" (subject) claim in the unsigned token, the attacker can impersonate any user or service account and execute unauthorized tool commands within the Rowboat environment.
