How to Fix CVE-2026-105859

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: 3.90.0 
npm install payload@3.90.0
payload fixed: 4.0.0-canary.34 
npm install payload@4.0.0-canary.34
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-2026-105859, 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 3.90.0), 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-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the 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 An attacker can submit a request to a specific endpoint that permits collection documents to be updated regardless of access control and field level access control. **You are affected if:** - You are configuring `orderable: true` with any collection or join field. ## Patches In the patched version access control is properly enforced. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
