Khoj is a self-hostable artificial intelligence app. Prior to 2.0.0-beta.23, an IDOR in the Notion OAuth callback allows an attacker to hijack any user's Notion integration by manipulating the state parameter. The callback endpoint accepts any user UUID without verifying the OAuth flow was initiated by that user, allowing attackers to replace victims' Notion configurations with their own, resulting in data poisoning and unauthorized access to the victim's Khoj search index. This attack requires knowing the user's UUID which can be leaked through shared conversations where an AI generated image is present. This vulnerability is fixed in 2.0.0-beta.23.

Khoj is an application that creates personal AI agents. The Automation feature allows a user to insert arbitrary HTML inside the task instructions, resulting in a Stored XSS. The q parameter for the /api/automation endpoint does not get correctly sanitized when rendered on the page, resulting in the ability of users to inject arbitrary HTML/JS. This vulnerability is fixed in 1.15.0.

Khoj is an application that creates personal AI agents. The Khoj Obsidian, Desktop and Web clients inadequately sanitize the AI model's response and user inputs. This can trigger Cross Site Scripting (XSS) via Prompt Injection from untrusted documents either indexed by the user on Khoj or read by Khoj from the internet when the user invokes the /online command. This vulnerability is fixed in 1.13.0.
