Executive Summary

The vulnerability exists in the Electron preload script used by Logseq. It exposes an API method that allows the renderer process to invoke IPC handlers without proper path validation.

This means that if an attacker can execute JavaScript in the renderer process (for example, through cross-site scripting (XSS) or a malicious plugin), they can exploit this flaw to read, write, or delete arbitrary files on the user's system.

Impact Analysis

This vulnerability can have serious impacts because it allows an attacker with JavaScript execution capabilities in the renderer process to manipulate files on your system without restriction.

• An attacker could read sensitive files, potentially exposing private data.
• They could write or modify files, which might lead to data corruption or the introduction of malicious code.
• They could delete important files, causing data loss or application malfunction.
