How to Fix CVE-2026-105805

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: 3.88.0 
npm install payload@3.88.0
payload fixed: 4.0.0-canary.27 
npm install payload@4.0.0-canary.27
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-2026-105805, 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 3.88.0), 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. 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 Under certain conditions, sorting readable records could reveal limited information about fields the requester was not permitted to read. You are affected if untrusted users can query a collection, control its sorting, and sort by protected fields. ### Patches Payload now applies field-level access checks to sort fields before executing queries. Users should upgrade to `>= 3.88.0` or `>= 4.0.0-canary.27`. ### Workarounds Upgrading is recommended. Until then, prevent untrusted users from controlling sort parameters or restrict their access to affected collections.
