How to Fix CVE-2026-105848

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.

@payloadcms/plugin-stripe fixed: 3.90.0 
npm install @payloadcms/plugin-stripe@3.90.0
@payloadcms/plugin-stripe fixed: 4.0.0-canary.34 
npm install @payloadcms/plugin-stripe@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 @payloadcms/plugin-stripe

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-105848, inspect your project dependencies using npm:

npm ls @payloadcms/plugin-stripe

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 @payloadcms/plugin-stripe 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-749: Exposed Dangerous Method or Function, where the product provides an applications programming interface (api) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted. 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 authenticated user could perform unintended Stripe operations through the optional Stripe REST proxy. **You are affected if ALL of these are true:** - Your application uses `@payloadcms/plugin-stripe`. - The optional Stripe REST proxy is enabled. - An authenticated user can reach the proxy. Deployments that do not enable the Stripe REST proxy are not affected. ## Patches Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`. ## Workarounds Upgrading to a patched version is recommended. If you cannot upgrade immediately, disable the Stripe REST proxy. If it must remain enabled, restrict access to trusted users and only the required Stripe operations.
