CVE-2026-9376 Details
Description
A vulnerability was determined in JPress up to 1.0.3. The affected element is an unknown function of the file /ucenter/article/doWriteSave of the component UCenter Article Submission Endpoint. Executing a manipulation of the argument id/userId can lead to improper authorization. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
An improper authorization vulnerability has been identified in JPress versions through 1.0.3, specifically within the UCenter Article Submission Endpoint. The issue arises in the POST /ucenter/article/doWriteSave endpoint, where insufficient verification allows authenticated users to manipulate the id or userId arguments. This lack of proper authorization can be exploited remotely, enabling low-privileged users to modify or overwrite articles belonging to others, provided they have access to a valid article ID.
Before updating an article, the application should verify that the current user is the owner of the article. This can be done by checking the article's user ID against the ID of the authenticated user. Unauthorized update attempts should be rejected with a 403 Forbidden response.
