Exploitation Conditions

No special conditions beyond network reachability - remote unauthenticated exploitation (PR:N/UI:N/AC:L) against affected ERPNext endpoints, which notably remain exploitable even when an administrator has DISABLED the corresponding feature, since the endpoints never enforce the authorization check. Limiting factors: the instance must be network-reachable by the attacker (internet-exposed instances are most at risk), and the achievable impact is bounded to creating records and enumerating availability (VI:L/VA:L) - it does not yield data disclosure (VC:N), code execution, or privilege escalation.

Impact

This is a moderate-severity missing-authorization flaw (CWE-862) in Frappe ERPNext. The only supplied severity signal is a CVSS 4.0 base score of 6.9 with vector AV:N/AC:L/AT:N/PR:N/UI:N and impacts VC:N/VI:L/VA:L - meaning network-reachable, low-complexity, unauthenticated exploitation with NO confidentiality impact and only LOW integrity and availability impact. The attack surface is genuinely easy to reach (no auth, no user interaction, low complexity), which raises its practical attractiveness, but the capped technical impact (creating records and enumerating availability, not data theft or full compromise) keeps overall risk moderate rather than critical. No EPSS score, no CISA KEV listing, and no POC indicator were provided in the input, so there is no evidence of active or probable exploitation - the exploitation status is 'no public exploit identified at time of analysis'. The signals are internally consistent (an unauthenticated network flaw with limited impact), so no conflict to flag; however, EPSS and SSVC/automatable data are MISSING, so exploitation likelihood cannot be quantified. Net: a real but lower-priority issue - patch on a normal cycle, prioritizing internet-exposed ERPNext instances, rather than emergency response.

Exploit ScenarioDerived

An attacker who can reach an ERPNext instance over the network sends unauthenticated HTTP requests directly to the affected endpoints, bypassing the missing authorization checks to create unwanted records (e.g., bookings/leads) and to enumerate availability data even on features an administrator has deliberately disabled. Because PR:N/UI:N/AC:L, no credentials, no victim interaction, and no special tooling are needed. No public exploit code was identified in the provided data.

AnalysisAIv1 – Oct 12, 2026

Unauthenticated remote attackers can invoke specific Frappe ERPNext endpoints that fail to enforce authorization checks, allowing them to create records and enumerate availability even when an administrator has disabled the corresponding feature. The flaw affects ERPNext before 15.110.0 and 16.x before 16.21.0, is classified as CWE-862 (missing authorization), and carries a moderate risk profile (6.9 CVSS v4.0; independent assessment CVSS 3.1 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) with impact bounded to low-integrity and low-availability effects and no data disclosure, code execution, or privilege escalation. No public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis; exploitation is nonetheless trivial for any network-reachable instance because no authentication, user interaction, or special conditions are required.

RemediationAI

Vendor-released patch: upgrade to ERPNext 15.110.0 or 16.21.0 (or later on the respective branch) as described in advisory GHSA-38rx-wm3g-39m3; because ERPNext is typically deployed via the Frappe bench toolchain, run the standard bench update/upgrade workflow and confirm the installed version after upgrading. Until patching is possible, the most effective compensating control is to remove network reachability for untrusted clients: place the ERPNext site behind a reverse proxy, VPN, or WAF that blocks anonymous access to /api/method/ paths (and to the specific record-creation endpoints named in the vendor advisory), accepting the trade-off that legitimate public/guest-facing API consumers and remote integrations will break. If guest-facing functionality is not required, disable anonymous access at the application layer by removing permissions from the 'Guest' role in the Role Permission Manager and disabling all 'Allow Guest' website settings, noting that this can break public portals, web forms, and unauthenticated self-service pages. Where feasible, restrict the ERPNext instance to trusted networks, monitor web-server and Frappe logs for unexpected record creation or availability-probing requests from unauthenticated sessions, and apply alerting on anomalous POST activity to API paths; none of these compensating controls fully eliminates the missing-authorization condition, so patching remains the definitive fix. The VulnCheck advisory at https://www.vulncheck.com/advisories/frappe-erpnext-before-15.110.0-missing-authorization-in-record-creation-endpoints should be reviewed for any endpoint-specific guidance.

Technical ContextAI · show details

ERPNext is an open-source ERP built on the Frappe Framework, a Python/Werkzeug-based web application that exposes business logic through 'whitelisted' methods reachable at /api/method/<dotted.path> and through REST resource endpoints. Normally Frappe enforces role- and document-level permissions (e.g., frappe.has_permission checks) before executing these methods, and system settings toggles are expected to disable corresponding features entirely. The underlying root cause here is CWE-862, missing authorization: certain record-creation and availability-enumeration endpoints omit the Frappe permission check altogether, so the guest/anonymous context is never validated against the role permission model. Consequently, turning off a feature in the administrator UI only hides or disables the standard call path-it does not remove the endpoint or make it refuse the request, leaving the function callable directly by anyone who can reach the HTTP interface. Exploitation requires only network reachability and standard HTTP requests; no credentials, CSRF bypass, or privileged role is needed. The CPE entry cpe:2.3:a:frappe:erpnext:*:*:*:*:*:*:*:* confirms the affected component is the ERPNext application itself across all version lines up to the fixed releases, and VulnCheck attributes the finding to missing authorization in record-creation endpoints, consistent with the CWE-862 classification and the bounded VI:L/VA:L impact assessed independently.
