A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access

How the Exploit Works
The exploit works by manipulating the object identifiers in the /api/users/{user-id} component. An attacker can edit their profile to assign themselves higher permissions or to change their household. This could potentially allow the attacker to gain unauthorized access to data or functionality that should be restricted to higher privilege levels.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited using an HTTP request:
PUT /api/users/{user-id} HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"user": {
"id": "{user-id}",
"role": "admin",
"household": "new_household"
}
}In this example, the attacker changes their role to “admin” and alters their household to “new_household”.
Mitigation Guidance
The primary recommended mitigation strategy is to apply the patch provided by the vendor. In the interim, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. It’s crucial to validate incoming requests to the /api/users/{user-id} endpoint to prevent unauthorized modification of user profiles.
