CVE-2025-55737 Details
Description
flaskBlog is a blog app built with Flask. In 2.8.0 and earlier, when deleting a comment, there's no validation of the ownership of the comment. Every user can delete an arbitrary comment of another user on every post, by simply intercepting the delete request and changing the commentID. The code that causes the problem is in routes/post.py.
A vulnerability exists in FlaskBlog versions through 2.8.0, allowing users to delete comments arbitrarily without ownership validation. By intercepting the delete request and modifying the commentID, any user can remove comments from others on any post. The issue arises in routes/post.py.
Implement a check to ensure that the user requesting the deletion owns the comment identified by the commentID before allowing the deletion to proceed.
