Payload disclosed two high-severity vulnerabilities affecting versions prior to 3.79.1 of payload and @payloadcms/graphql, including an SQL injection issue tracked as CVE-2026-34747 and an unvalidated input flaw in password recovery endpoints tracked as CVE-2026-34751. The SQL injection bug stems from improper validation of certain request inputs and could let an attacker influence query execution to expose or modify collection data. The password recovery flaw could allow an unauthenticated attacker to perform actions on behalf of a user who has initiated a password reset.
The vulnerabilities were patched in Payload 3.79.1, with advisories mapping the issues to CWE-89 for SQL injection and CWE-640 and CWE-472 for the password recovery weakness. The SQL injection issue carries a CVSS v3.1 vector of AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N, while the password recovery flaw is rated AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating significant confidentiality and integrity risk for exposed deployments that have not yet upgraded.
