CVE-2026-47765 in Frappe
Summary
by MITRE • 08/07/2026
Frappe is a full-stack web application framework. Prior to 15.110.0 and 16.20.0, the restore and bulk_restore 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.

The vulnerability described affects Frappe, a comprehensive full-stack web application framework widely used for building business applications. This security flaw exists in versions prior to 15.110.0 and 16.20.0 where the restore and bulk_restore endpoints fail to enforce proper document permission validation. The core issue stems from inadequate access control mechanisms that allow authenticated users to bypass authorization checks when attempting to restore deleted documents. This represents a significant privilege escalation vulnerability within the framework's data management capabilities.
The technical implementation flaw occurs at the endpoint level where the restore functionality does not properly verify whether the requesting user possesses sufficient permissions to restore the targeted document. According to CWE classification, this manifests as a weakness in authorization checking mechanisms, specifically CWE-285 which addresses insufficient authorization. The vulnerability enables unauthorized restoration of documents that should be restricted to specific user roles or groups, potentially exposing sensitive data or allowing manipulation of application state. This issue falls under the ATT&CK technique T1078.004 for valid accounts and privilege escalation through unauthorized access.
The operational impact of this vulnerability is substantial as it allows authenticated attackers to restore deleted content without proper authorization, potentially leading to data exposure, information leakage, or system state manipulation. Attackers could restore documents containing sensitive business information, personal data, or confidential communications that were intentionally deleted for security or compliance reasons. This capability undermines the framework's access control model and could result in regulatory violations, data breaches, or unauthorized system modifications.
Mitigation strategies should focus on implementing proper permission validation at the restore endpoints, ensuring that all restoration operations require appropriate authorization checks before proceeding. Organizations using affected Frappe versions should immediately upgrade to 15.110.0 or 16.20.0 where this vulnerability has been patched. Additional defensive measures include implementing comprehensive access control logging, monitoring restoration activities, and conducting regular security assessments of document management functionalities. The fix implemented in the newer versions addresses the root cause by enforcing proper document permission checks during restore operations, aligning with industry best practices for secure application development and authorization enforcement.
