Summary
Payload: Polymorphic join queries could disclose hidden fields
Workarounds
There is no complete workaround. Restricting read access to sensitive collections reduces exposure but does not replace upgrading.
Impact
A user with query access could use polymorphic join filters to infer hidden or read-restricted field values, including password-reset tokens.
You are affected if:
- You use an affected Payload version.
- Users can query a collection with a polymorphic join to sensitive fields.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Frequently Asked Questions
- What is CVE-2026-105847? CVE-2026-105847 is a high-severity security vulnerability in payload (npm), affecting versions >= 3.0.0, < 3.90.0. It is fixed in 3.90.0, 4.0.0-canary.34.
- Which versions of payload are affected by CVE-2026-105847? payload (npm) versions >= 3.0.0, < 3.90.0 is affected.
- Is there a fix for CVE-2026-105847? Yes. CVE-2026-105847 is fixed in 3.90.0, 4.0.0-canary.34. Upgrade to this version or later.
- Is CVE-2026-105847 exploitable, and should I be worried? Whether CVE-2026-105847 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-105847 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
