flaskBlog arbitrary comment delete
Summary
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.

Title
flaskBlog Stored XSS Vulnerability
Summary
flaskBlog is a blog app built with Flask. In 2.8.0 and earlier, when creating a post, there's no validation of the content of the post stored in the variable "postContent". The vulnerability arises when displaying the content of the post using the | safe filter, that tells the engine to not escape the rendered content. This can lead to a stored XSS inside the content of the post. The code that causes the problem is in template/routes.html.

Title
flaskBlo Authorization Bypass
Summary
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.
Severity ?

CVE-2024-22414 (GCVE-0-2024-22414)

Vulnerability from cvelistv5 – Published: 2024-01-17 20:25 – Updated: 2025-06-17 21:19
VLAI?
Title
User profile page vulnerable to Cross Site Scripting (XSS) in flaskBlog
Summary
flaskBlog is a simple blog app built with Flask. Improper storage and rendering of the `/user/<user>` page allows a user's comments to execute arbitrary javascript code. The html template `user.html` contains the following code snippet to render comments made by a user: `<div class="content" tag="content">{{comment[2]|safe}}</div>`. Use of the "safe" tag causes flask to _not_ escape the rendered content. To remediate this, simply remove the `|safe` tag from the HTML above. No fix is is available and users are advised to manually edit their installation.

Improper storage and rendering of the `/user/\u003cuser\u003e` page allows a user\u0027s comments to execute arbitrary javascript code. The html template `user.html` contains the following code snippet to render comments made by a user: `\u003cdiv class=\"content\" tag=\"content\"\u003e{{comment[2]|safe}}\u003c/div\u003e`. Use of the \"safe\" tag causes flask to _not_ escape the rendered content. To remediate this, simply remove the `|safe` tag from the HTML above. No fix is is available and users are advised to manually edit their installation."
