How to Fix CVE-2026-105852

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-2026-105852, 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action.
