Frappe 15.11.0 through 16.32.0 stores and renders the workspace card description without XSS filtering. The description field of the Workspace Link doctype is declared with "ignorexssfilter": 1 in frappe/desk/doctype/workspacelink/workspacelink.json, and sanitizecontent() in frappe/model/basedocument.py skips any field carrying that flag, so the value is stored exactly as submitted. frappe.desk.desktop.getdesktoppage returns it unchanged, and LinksWidget.setbody() in frappe/public/js/frappe/widgets/linkswidget.js interpolates it into a Bootstrap popover created with html: true, by way of the () translation helper, which performs no HTML escaping. A user holding the Workspace Manager role can therefore place arbitrary markup in a public workspace's card description and have it execute in the session of any desk user who opens that workspace and hovers the description, including higher-privileged users, allowing session token theft and authenticated requests as the victim. The flag is removed on the development branch but remains present in the shipped 15.x and 16.x release lines, so no released version carries the fix.

Frappe is a full-stack web application framework written in Python and JavaScript. Prior to version 15.115.0, an access control bypass in the REST API allows a user to read data from Linked DocTypes that they are not authorized to access. When a document references another document through a Link field, the framework does not consistently enforce the linked DocType's own permissions when the record is retrieved through the REST API, so a low-privileged authenticated user can obtain fields from linked records outside their permitted scope. This issue is fixed in version 15.115.0.

Frappe is a full-stack web application framework. Prior to 15.114.0 and 16.26.0, the approve and authorize functions in frappe/integrations/oauth2.py allow the OAuth2 consent flow to proceed without restricting approve to POST, without a csrftoken in frappe/templates/includes/oauthconfirmation.html, and without scoping an active OAuth token check to the requesting client. An attacker can cause an authenticated user to approve an OAuth grant or reuse authorization state for the wrong client, exposing data and permitting actions within the granted scopes. This issue is fixed in versions 15.114.0 and 16.26.0.

Frappe is a full-stack web application framework. Prior to 15.115.0 and 16.27.0, the public request-data web form and PersonalDataDownloadRequest class in frappe/website/doctype/personaldatadownloadrequest/personaldatadownloadrequest.py return distinguishable response shapes for registered and unregistered email addresses, including the username field and persistence behavior. A remote attacker can compare the responses to enumerate registered users. This issue is fixed in versions 15.115.0 and 16.27.0.

Frappe is a full-stack web application framework. In version 16.31.0 and earlier, the whitelisted frappe.model.workflow.bulkworkflowapproval endpoint in frappe/model/workflow.py accepts safe HTTP methods for state-changing workflow approvals because the endpoint is not restricted to POST. An attacker can induce an authenticated victim browser to submit an approval action with the victim privileges. No released fixed version is available as of this review.

Frappe is a full-stack web application framework. In version 16.31.0 and earlier, frappe.client.setvalue in frappe/client.py checks a dictionary supplied through the fieldname parameter against forbidden standard and child-table fields before parsing the dictionary into individual field names. An authenticated caller can exploit this type confusion to mass-assign protected fields through the client endpoint. No released fixed version is available as of this review.

Frappe is a full-stack web application framework. In version 16.31.0 and earlier, the whitelisted togglelike and markasseen endpoints in frappe/desk/like.py and frappe/desk/doctype/note/note.py do not enforce read permission before modifying likedby metadata or a Note seen state. An authenticated user can interact with documents or notes that the user cannot read, disclosing resource existence and modifying resource-associated metadata. No released fixed version is available as of this review.

ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.111.0 and 16.22.0, limited authenticated users can cross a permission boundary in Frappe safe execution because frappe.rendertemplate is exposed without forcing restrictglobals, allowing server-side template injection and remote code execution. This issue is fixed in versions 15.111.0 and 16.22.0.

Frappe is a full-stack web application framework. Versions 14.96.9 and below, and 15.0.0 through 15.71.0 have an insecure endpoint parameter that is vulnerable to error-based SQL Injection through lack of validation. Sensitive information such as versioning can be retrieved. This issue is fixed in versions 14.96.10 and 15.72.0.

Frappe is a full-stack web application framework. Prior to 16.20.0 and 15.112.0, unrestricted access to a Document Follow API (updatefollow) is possible for an authenticated user. This issue is fixed in versions 16.20.0 and 15.112.0.

Frappe is a full-stack web application framework. Prior to 16.19.0 and 15.109.0, Data Import does not escape imported column headers before rendering previews and results, allowing an authenticated importer to persist script content that executes when another user views the import interface. This issue is fixed in versions 16.19.0 and 15.109.0.

Frappe is a full-stack web application framework. Prior to 16.18.0, the Workspace Save API accepts a controlled workspace identifier from any authenticated user without enforcing workspace ownership, allowing modification of another user's private workspace and persistent script injection. This issue is fixed in version 16.18.0.

Frappe is a full-stack web application framework. Prior to 15.110.0 and 16.20.0, the restore and bulkrestore endpoints do not apply the appropriate document permission checks, allowing an authenticated user to restore deleted documents without the required authorization. This issue is fixed in versions 15.110.0 and 16.20.0.

SQL injection in Frappe's ERPNext, versions ERPNext 15.107.0 and Frappe 15.107.2. The application constructs SQL queries through direct string interpolation using str.format() without employing parameterized queries, allowing the name (docname) of a Supplier record containing SQL metacharacters to be interpreted as part of the query. Exploitation of this vulnerability could allow an authenticated user with low privileges to execute arbitrary SQL queries, bypass Frappe’s access restrictions (DocPerm), extract confidential information from the database—including fragments of the administrator’s password hash—and access other sensitive data, such as credentials, integration tokens, or financial information.

A Server-Side Request Forgery (SSRF) vulnerability exists in the Print Format functionality of ERPNext v16.0.1 and Frappe Framework v16.1.1, where user-supplied HTML is insufficiently sanitized before being rendered into PDF. When generating PDFs from user-controlled HTML content, the application allows the inclusion of HTML elements such as <iframe> that reference external resources. The PDF rendering engine automatically fetches these resources on the server side. An attacker can abuse this behavior to force the server to make arbitrary HTTP requests to internal services, including cloud metadata endpoints, potentially leading to sensitive information disclosure.

Frappe is a full-stack web application framework. Prior to 16.14.0 and 15.104.0, Frappe allows unrestricted Doctype access via API exploit.

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to 2.46.0, a vulnerability has been identified in Frappe Learning where quiz scores can be modified by students before submission. The application currently relies on client-side calculated scores, which can be altered using browser developer tools prior to sending the submission request. While this does not allow modification of other users’ data or privilege escalation, it compromises the integrity of quiz results and undermines academic reliability. This issue affects data integrity but does not expose confidential information or allow unauthorized access to other accounts. This vulnerability is fixed in 2.46.0.

ERPNext v15.103.1 and before is vulnerable to Cross Site Scripting (XSS) in the Email Template engine. An attacker with permission to create or edit email templates can inject malicious JavaScript code that are executed on the victim's browser when the template is applied.
