How to Fix CVE-2026-34747

To remediate this vulnerability, upgrade all affected Payload dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

payload fixed: 3.79.1 
npm install payload@3.79.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls payload

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-34747, inspect your project dependencies using npm:

npm ls payload

Analyze the terminal output to locate any version of Payload in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.79.1), your application is affected.

Note: The npm ls payload command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Payload, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Certain request inputs were not properly validated. An attacker could craft requests that influence SQL query execution, potentially exposing or modifying data in collections. ### Patches This issue has been fixed in **v3.79.1** and later. Query input validation has been hardened. Upgrade to **v3.79.1 or later**. ### Workarounds Until developers can upgrade: - Limit access to endpoints that accept dynamic query inputs to trusted users only. - Validate or sanitize input from untrusted clients before sending it to query endpoints.
