Prior to version 3.79.1, a critical vulnerability (CVE-2026-34751) exists in the \u003ccode\u003e@payloadcms/graphql\u003c/code\u003e and \u003ccode\u003epayload\u003c/code\u003e components concerning the password recovery flow. This flaw allows an unauthenticated attacker to potentially perform actions as a legitimate user who has initiated a password reset process. The vulnerability arises from improper handling of password reset tokens or insufficient validation during the password reset process. The maintainers addressed this issue in version 3.79.1. Organizations using affected versions of Payload CMS should upgrade immediately to prevent potential account compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a valid username on the Payload CMS instance.\u003c/li\u003e\n\u003cli\u003eAttacker initiates the password reset process for the target user via the CMS login page.\u003c/li\u003e\n\u003cli\u003eThe CMS sends a password reset email to the valid user, containing a unique password reset link.\u003c/li\u003e\n\u003cli\u003eThe attacker intercepts or gains access to the password reset link (e.g., via sniffing network traffic, although unlikely in a modern HTTPS-enabled setup, or social engineering).\u003c/li\u003e\n\u003cli\u003eAttacker uses the intercepted password reset link to access the password reset form.\u003c/li\u003e\n\u003cli\u003eDue to the vulnerability, the attacker can successfully change the password without proper validation or authorization checks beyond the initial link.\u003c/li\u003e\n\u003cli\u003eThe attacker sets a new password for the user account.\u003c/li\u003e\n\u003cli\u003eThe attacker logs into the Payload CMS using the compromised account credentials, gaining unauthorized access and potentially escalating privileges depending on the account\u0026rsquo;s role.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-34751 allows an unauthenticated attacker to compromise user accounts within the Payload CMS.
