CVE-2025-55734flaskBlo Authorization Bypass
Medium 6.9
In plain English
A medium-severity missing authorization in FlaskBlog from DogukanUrker. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 32% of all known vulnerabilities).
Official 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.
