CVE-2026-7782
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was detected in CodeCanyon Perfex CRM up to 3.4.1. This affects the function Clients::project of the file application/controllers/Clients.php of the component Tenant Handler. The manipulation of the argument ID results in authorization bypass. The attack may be performed from remote. The exploit is now public and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAuthorization bypass vulnerability in Perfex CRM's Clients::project function allows attackers to access projects belonging to other tenants by manipulating the ID parameter, bypassing tenant isolation checks in the Tenant Handler component.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Perfex CRM installationIdentify if the Perfex CRM application is deployed in your environment by checking for the characteristic directory structure and index.php entry pointAffected if Perfex CRM is present and accessible
-
Determine installed versionLocate the version file or check the admin panel for the current Perfex CRM version numberAffected if Version is unknown or cannot be verified as 3.4.2 or later
-
Verify multi-tenant configurationCheck if the Tenant Handler component is active by examining tenant configuration settings or database tenant recordsAffected if Multi-tenant functionality is enabled and multiple tenant organizations exist in the system
-
Inspect Clients::project function authorization logicExamine the source code of the Clients::project function to determine if tenant ID validation is performed before returning project dataAffected if The function lacks proper tenant boundary validation or allows ID parameter manipulation without tenant verification
-
Test tenant isolation enforcementUsing an authorized client account from one tenant, attempt to access a project by directly manipulating the ID parameter to reference a project from a different tenantAffected if The system returns project data from a different tenant, indicating the isolation bypass is present
The environment is affected if Perfex CRM is running with multi-tenancy enabled and the Clients::project function permits access to projects across tenant boundaries without proper authorization validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch (version 3.4.2+) when available; until then, implement proper tenant-scoped authorization validation in the project function to ensure users can only access projects within their tenant boundary.
