Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is a server-side access control bypass in a web framework that allows an authenticated low-privileged user to grant elevated document permissions they do not possess, directly enabling exploitation of a software flaw for privilege escalation (T1068).
NVD Description
Frappe is a full-stack web application framework. Prior to versions 15.98.0 and 14.100.0, due to a lack of validation when sharing documents, a user could share a document with a permission that they themselves didn't have. This issue has been…

Deeper analysisAI
CVE-2026-29077 is a vulnerability in Frappe, a full-stack web application framework, stemming from a lack of validation when sharing documents. In versions prior to 15.98.0 and 14.100.0, a user could share a document with permissions that they themselves did not possess, enabling improper privilege escalation through document sharing. The issue is rated with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N) and is associated with CWE-284 (Improper Access Control) and CWE-602 (Client-Side Enforcement of Server-Side Security).
An authenticated user with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows the attacker to grant elevated permissions on documents to other users, resulting in high integrity impact by bypassing intended access controls, low confidentiality impact, and no availability disruption.
The Frappe security advisory at https://github.com/frappe/frappe/security/advisories/GHSA-5h4c-9p23-4c3m confirms the issue has been addressed in versions 15.98.0 and 14.100.0, recommending immediate upgrades to these patched releases for mitigation.
