An arbitrary file upload vulnerability in the Attachments module of Frappe Framework v15.89.0 allows attackers to execute arbitrary code via uploading a crafted XML file.

Frappe may be vulnerable remote code execution due to server-side template injection

Frappe is a full-stack web application framework. Prior to versions 14.99.6 and 15.88.1, an authenticated user with specific permissions could be tricked into accessing a specially crafted link. This could lead to a malicious template being executed on the server, resulting in remote code execution. Versions 14.99.6 and 15.88.1 fix the issue. No known workarounds are available.

Frappe CRM 1.53.1 — Multiple SQL Injections in Dashboard Controller

Multiple SQL Injections in Frappe CRM Dashboard Controller due to unsafe concatenation of user-controlled parameters into dynamic SQL statements. This issue affects Frappe CRM: 1.53.1.

Frappe authenticated users can execute XSS through form description fields

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Versions prior to 2.42.0 allow authenticated users to add malicious HTML and JavaScript through description fields in the Job, Course and Batch forms. This issue is fixed in version 2.42.0.

Frappe Authenticated Users can Execute JavaScript through its Job Form

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Versions prior to 2.42.0 allowed authenticated attackers to enter JavaScript through the Company Website field of the Job Form, exposing users to an XSS attack. The script could then be executed in the browsers of users who opened the malicious job posting. This issue is fixed in version 2.42.0.

Frappe LMS is Missing Server-Side Authorization in Business Logic

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to 2.41.0, a flaw in the server-side authorization logic allowed authenticated users to perform actions beyond their assigned roles across multiple features. Because the affected endpoints relied on client-side or UI-level checks instead of enforcing permissions on the server, users with low-privileged roles (such as students) could perform operations intended only for instructors or administrators via directly using the API's. This vulnerability is fixed in 2.41.0.

In ERPNext v15.83.2 and Frappe Framework v15.86.0, improper validation of uploaded SVG avatar images allows attackers to embed malicious JavaScript. The payload executes when an administrator clicks the image link to view the avatar, resulting in stored cross-site scripting (XSS). Successful exploitation may lead to account takeover, privilege escalation, or full compromise of the affected ERPNext instance.

Frappe has the possibility of SQL Injection due to improper validations

Frappe is a full-stack web application framework. Prior to 15.86.0 and 14.99.2, a certain endpoint was vulnerable to error-based SQL injection due to lack of validation of parameters. Some information like version could be retrieved. This vulnerability is fixed in 15.86.0 and 14.99.2.

Frappe vulnerable to a path traversal allowing reading certain files

Frappe is a full-stack web application framework. Prior to 15.86.0 and 14.99.2, certain requests were vulnerable to path traversal attacks, wherein some files from the server could be retrieved if the full path was known. Sites hosted on Frappe Cloud, and even other setups that are behind a reverse proxy like NGINX are unaffected. This would mainly affect someone directly using werkzeug/gunicorn. In those cases, either an upgrade or changing the setup to use a reverse proxy is recommended. This vulnerability is fixed in 15.86.0 and 14.99.2.

Frappe user was able to access the submission of other students

Frappe Learning is a learning system that helps users structure their content. Starting in version 2.0.0 and prior to version 2.41.0, users were able to access the submissions made by other students The issue has been fixed in version 2.41.0 by ensuring proper roles and redirecting if accessed via direct URL.

Frappe LMS revoking access did not show immediate effect as roles were cached

Frappe Learning is a learning system that helps users structure their content. Starting in version 2.0.0 and prior to version 2.41.0, when admins revoked a role from the user, the effect was not immediate because of caching. The issue has been fixed in version 2.41.0 by ensuring the cache is cleared after roles are updated.

Frappe Learning allowed students to access the Quiz Form via direct URL

Frappe Learning is a learning management system. A security issue was identified in Frappe Learning 2.39.1 and earlier, where students were able to access the Quiz Form if they had the URL.

Frappe Learning users were able to add HTML through input fields in the Job Form

Frappe Learning is a learning system that helps users structure their content. In Frappe Learning 2.39.1 and earlier, users were able to add HTML through input fields in the Job Form.

Frappe has an Open Redirect on Login Page

Frappe is a full-stack web application framework. Prior to 14.98.0 and 15.83.0, an open redirect was possible through the redirect argument on the login page, if a specific type of URL was passed in. This vulnerability is fixed in 14.98.0 and 15.83.0.

Frappe had attachments made by students to their assignments of type Text set to public

Frappe Learning is a learning system that helps users structure their content. In versions prior to 2.38.0, the system did stored the attachments uploaded by the students in their assignments as public files. This issue potentially exposed student-uploaded files to the public. Anyone with the file URL could access these files without authentication. The issue has been fixed in version 2.38.0 by ensuring all student-uploaded assignment attachments are stored as private files by default.

Frappe Learning vulnerable to Malicious Content upload via Profile bio field

Frappe Learning is a learning system that helps users structure their content. In versions 2.34.1 and below, there is a security vulnerability in Frappe Learning where the system did not adequately sanitize the content uploaded in the profile bio. Malicious SVG files could be used to execute arbitrary scripts in the context of other users.

However, the release notes on GitHub do not mention them.

Frappe Learning Holds Potential for Malicious SVG Upload in Image Upload Feature

Frappe Learning is a learning system that helps users structure their content. In versions 2.33.0 and below, the image upload functionality did not adequately sanitize uploaded SVG files. This allowed users to upload SVG files containing embedded JavaScript or other potentially malicious content. Malicious SVG files could be used to execute arbitrary scripts in the context of other users. A fix for this issue is planned for version 2.34.0.
