Arbitrary File Access via Exposed IPC Method in Logseq Electron Preload Script
CVE-2026-47899 affects Logseq's Electron application. The Electron preload script exposes an API method that allows the renderer process to invoke IPC handlers without proper path validation. If an attacker obtains JavaScript execution in the renderer context, they can abuse this exposed functionality to perform filesystem operations on attacker-chosen paths. The reported consequence is arbitrary file read, write, and deletion on the local system. The issue was confirmed on Logseq v0.10.15; the status of other versions is unknown because the issue had not been addressed by a patch at the time of disclosure.
