CVE-2026-124573 Details
Description
A vulnerability was found in logseq 2.0.1/2.0.2. This affects the function validate-auth-token of the file src/electron/electron/server.cljs of the component Local HTTP API. The manipulation results in missing authentication. The attack may be performed from remote. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
A vulnerability exists in Logseq versions 2.0.1 and 2.0.2, specifically within the local HTTP API server embedded in the desktop application. The issue arises because the API server's authentication can be completely bypassed when the token list is empty, which is the default state. This allows for unauthenticated requests to be sent to the API, exploiting several high-privilege SDK functions. The vulnerability can be reproduced by opening an attacker-controlled web page that sends cross-origin requests to the API, taking advantage of the CORS policy that allows any origin to access the API responses.
Users can set a token in the API server settings to protect against this vulnerability. Logseq should also be updated to a version where this vulnerability is fixed.
