Overview

CVE-2025-55734 is a medium-severity vulnerability. It was published on August 19, 2025 and has a CVSS 3.1 base score of 6.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

flaskBlog is a blog app built with Flask. In 2.8.0 and earlier, the code checks if the userRole is "admin" only when visiting the /admin page, but not when visiting its subroutes. Specifically, only the file routes/adminPanel.py checks the user role when a user is trying to access the admin page, but that control is not done for the pages routes/adminPanelComments.py and routes/adminPanelPosts.py. Thus, an unauthorized user can bypass the intended restrictions, leaking sensitive data and accessing the following pages: /admin/posts, /adminpanel/posts, /admin/comments, and /adminpanel/comments.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
