How to Fix CVE-2026-105846

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
@payloadcms/next fixed: 3.88.0 
npm install @payloadcms/next@3.88.0
@payloadcms/next fixed: 4.0.0-canary.27 
npm install @payloadcms/next@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-2026-105846, 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-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. 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, an attacker can craft a redirect link that sends a guest user to an untrusted destination after authenticating. ### Patches Users should upgrade Payload packages to `>= 3.88.0` or `>= 4.0.0-canary.27`. ### Workarounds Upgrading is recommended. Until then, remove user-controlled redirect values from authentication flows or restrict them to known local paths.
