The vulnerability resides in versions prior to 1.2.7 and 1.3.0. It allows a non-staff authenticated user to elevate their account privileges to a staff level. This is achieved by sending a specially crafted POST request to the user\u0026rsquo;s account endpoint. The root cause is due to improperly configured write permissions on the API endpoint, enabling unauthorized modification of the user\u0026rsquo;s staff status. Upgrading to versions 1.2.7 or 1.3.0 resolves this issue. This vulnerability allows attackers to gain elevated privileges within the InvenTree system, potentially leading to unauthorized data access, modification, or other malicious activities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker registers a standard user account on the InvenTree platform.\u003c/li\u003e\n\u003cli\u003eThe attacker authenticates to obtain a valid session token or API key.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a POST request to the user account endpoint, typically \u003ccode\u003e/api/user/\u0026lt;user_id\u0026gt;/\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe POST request includes a data payload modifying the \u003ccode\u003eis_staff\u003c/code\u003e field to \u003ccode\u003etrue\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe attacker sends the malicious POST request to the InvenTree server.\u003c/li\u003e\n\u003cli\u003eDue to the improperly configured write permissions, the server accepts the request and updates the user\u0026rsquo;s \u003ccode\u003eis_staff\u003c/code\u003e status in the database.\u003c/li\u003e\n\u003cli\u003eThe attacker\u0026rsquo;s account is now elevated to staff level, granting access to administrative functions and data.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-35476 allows an attacker to escalate their privileges from a standard user to a staff user within the InvenTree system.
