Descripción técnica

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.5.2 via the GET /wp-json/gh/v4/contacts/<id> REST endpoint. The endpoint's permission callback checks only the role-level view_contacts capability and read_single() returns the full contact record by sequential integer ID without the object-level view_contact ownership check applied elsewhere in the codebase. This makes it possible for authenticated attackers holding view_contacts but not view_others_contacts — notably Groundhogg's built-in Sales Rep role, designed to see only its own contacts — to read any contact record on the site, including PII, contact meta, owner IDs, the admin edit URL, and (for contacts linked to a WordPress user) that user's full capability set.

——0jshERP through 3.6 fails to validate object ownership in by-id info, update, and delete endpoints across multiple resource types. Authenticated users can read, modify, and delete other users' business objects by submitting direct object identifiers without authorization checks.2h CVE-2026-944945.0 MED

——0jshERP through 3.6 contains a tenant isolation bypass vulnerability that allows authenticated users to read other tenants' records via the GET /tenant/info endpoint. Attackers can iterate the primary key to enumerate and access sensitive tenant data including login names, validity dates, user quotas, and enabled state across all platform tenants.2h CVE-2026-617484.3 MED

——0InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, ReportPrint at POST /api/report/print/ and LabelPrint at POST /api/report/label/print/ require authentication but do not call users.permissions.check_user_permission for the caller's per-model view role before selecting objects by primary key and rendering them with a chosen template. Because default templates exist for major business models and DataOutput stores the generated artifact for the requesting user, a role-less or unrelated-role account can enumerate object identifiers and download reports containing purchase, sales, part, bill-of-materials, stock, build, supplier, customer, pricing, and inventory data that the corresponding detail APIs would deny. This issue is fixed in version 1.4.0.2h CVE-2026-617474.3 MED

——0InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, the /api/importer/row/ and /api/importer/mapping/ endpoints do not scope DataImportRow and DataImportColumnMap querysets to the owner of the associated DataImportSession. Any authenticated user, including an account with no assigned roles, can supply another user's import session identifier and retrieve that session's row_data and data fields together with its column mappings. This exposes the full contents of data staged for import across users, although the InvenTree threat model treats authenticated instance users as trusted. This issue is fixed in version 1.4.0.2h CVE-2026-617446.5 MED

——0InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, POST /api/barcode/ accepts an attacker-synthesized internal JSON barcode containing a lowercase model label and integer primary key, while BarcodeView uses IsAuthenticatedOrReadScope and requires only authentication or a general read scope. The built-in barcode plugin selects the object with model.objects.get(pk=...), and InvenTreeBarcodeMixin.format_matched_response() returns the complete model serializer output as instance without checking the caller's per-model view role. A low-privilege user can enumerate primary keys for parts, stock, locations, supplier and manufacturer parts, orders, and builds to disclose commercially sensitive inventory, pricing, supplier, customer, and order data. This issue is fixed in version 1.4.0.2h CVE-2026-691906.3 MED

——0Graylog is a free and open log management platform. From 6.3.0 until 6.3.14, 7.0.9, and 7.1.4, the view update API for saved searches and dashboards permits a user with edit permission but without entity ownership to include a shareRequest that grants owner permissions to an arbitrary account. The selected account can then delete the saved search or dashboard or remove the original owner's access. Graylog Cloud was patched before the advisory was published. This issue is fixed in versions 6.3.14, 7.0.9, and 7.1.4.2h
