CyberRota Analysis

AI-Generated

The Kibana Agent Builder's A2A JSON-RPC API endpoint is vulnerable due to improper handling of user-supplied identifiers, allowing an authenticated user with read privileges to overwrite another user's conversation. This results in the original owner losing access to their conversation and its history, impacting the integrity and availability of the affected data. Organizations using Kibana Agent Builder should prioritize addressing this vulnerability to prevent unauthorized data manipulation within their environments.

Original NVD Description

Kibana Agent Builder A2A JSON-RPC API endpoint derives the identifier of a stored conversation from a user-supplied input, and the ownership check on that identifier does not distinguish between a conversation that does not exist and one that exists but belongs to another user. As a result, an authenticated user holding only the Agent Builder read privilege can supply an identifier already in use by another user in the same space and cause that user's conversation to be replaced and reassigned to the requesting account. The original owner permanently loses access to the conversation and its history. The impact is limited to loss of integrity and availability of the affected conversation; the attacker does not read the overwritten content.
